TANKS! README.TXT Created May 14 1994 Updated October 27th 1995 This file contains information not available at the time that the game manual was printed. Many of the rules changes reflect player requested changes incorporated in the game since the release of version 1.0. This document is valid only for TANKS! version 1.30 and later. The history of changes to the TANKS! game program is now listed in HISTORY.TXT. Players of previous versions of the game should look through the history file for a list of recent changes. COMMAND LINE PARAMETERS TANKS! will accept several command line parameters. Ordinarily you won't have to worry about this, but they can be handy under certain special circumstances. DEBUG : Enables a special game error checking and data recording mode that should only be used at SSI's request. FM : Forces the game to use FM sounds if your sound card supports them, even if your sound card normally plays digitized sounds. This will free up about 20K of conventional memory for use by TSR's, etc. MONO : Forces monaural sound on stereo capable sound cards. Use this if you don't care for the stereo effects. Other than balancing the sound volume from both speakers, there is no detrimental effect on sound quality. QUICK : Disables the time delays built into the combat results reports. Using this will speed up the game considerably, but you will have to check the results of combat manually by examining the units involved after the combat. QUIET : Turns off the intro music only. VANILLAMOUSE : Some obsolete mouse drivers may have problems with the game. If you encounter graphics "glitches" around the edge of the map try using this parameter until you can update your mouse driver software. Using this parameter fixes the shape of the mouse to an arrowhead and decreases mouse sensitivity in some areas. BIGSCALE : An experimental 500 meter game scale has been implemented. If you start the game with the "bigscale" command line parameter, all weapon ranges and sighting distances will be halved for the duration of the current play session. Movement rates are not affected. This feature is intended to allow players to create larger scale battles featuring company and battalion level units, and should be considered strictly experimental. HELP : Shows a list of all functional command line parameters. OLDBAIL: Modifies bailout rules for infantry in units hit by direct fire. See history.txt for details. STATIC: Turns off variability in reinforcements and weather. See history.txt for details. If you decide to use one or more of these commands, you just type them after the word TANKS but before you hit the key. Example: Typing "TANKS FM VANILLAMOUSE " would start the game with the fixed mouse cursor and fm sounds only. INFO MENU Addition: An "Info / Combat Time Delays" item allows players to select from a range of time delays for displaying combat results. The display called up by the "Formations" item not only displays information on various formations owned by the current player. This display can be used to issue formation wide auto or hold fire orders, and shows considerable detail on all units in any given formation. PLAY MENU Addition: The "Show All Visible" item controls display of map graphics indicating which hexes can be seen, or have been spotted by the current player. Visible hexes are indicated by a crosshair graphic. The ownership of each visible hex is indicated by the color of the crosshair. "RANDOM" ORDERS OF BATTLE Clarification: TANKS! automatically creates orders of battle when it makes random scenarios and when you use the random forces button in the editor. These orders of battle aren't really "random". They are based on real unit organizations for each force represented in the game. Equipment assignments are heavily influenced by the historical overall mobility of the force. Low mobility forces tend to have lots of dismounted infantry. High mobility forces tend to have lots of tanks and mechanized support. If you wish, you can override historical force mobilities with the mobility buttons that pop up during random scenario and OOB creation. When you ask the program to create a random scenario, you will be asked to choose tiny, small, medium, or large forces for each side. These correspond roughly to 10, 30, 60, or 90 units per side. But in order to balance the scenario, the force sizes you request may be modified. This is particularly likely if you select forces with very different levels of technology or quality. For example, if you request a "tiny" random battle between 1918 Germans and 1991 Americans, the scenario balancing routine will probably create a very large German force. COMMAND RULES Addition: Formations with control ratings lower than 7 are more susceptible to forced "reorganization" (and loss of a turn) than those with higher control ratings. This reflects the relative scarcity of communications equipment and rigidity of command structure in forces with low control ratings: 1940 French, Italians, Chinese, Iraqis, pre '67 Soviets, and all 1918 armies. MOVING YOUR UNITS Addition: Any unit with a non-zero movement rate, which has not already moved this turn, can always move at least one hex regardless of movement cost. Unarmed units will not launch close assaults. In order to be considered "armed", the unit must have at least one weapon mounted on its "top" equipment type. Out of ammo units will be allowed to assault, but their chance of success is small. Mounted, non flying units dismount at start of the second round of combat in close assaults. DIRECT FIRE Additions: If the target unit is in a fort hex, there is a 40% chance that any direct fire shot will miss. If the target is in a depression hex, there is a 10% chance that any direct fire shot will miss. Parent formation morale and control ratings affect the accuracy of a unit's fire. Units belonging to formations with poor morale and control ratings will not hit their targets as often as units belonging to higher quality formations. After a mounted unit takes losses due to direct fire, surviving infantry and light weapons squads may immediately dismount. This always happens if more than one vehicle is destroyed. If only one vehicle is destroyed, the unit will remain mounted unless it fails a morale check. Change: When firing at a unit composed of an armed transport and some other type of equipment, the transport will always be shot at first. Your units will only fire on unarmed transports if they (the transports) are the top equipment type in the target unit. INDIRECT FIRE Addition: In addition to unspotted intersection, town, and village hexes, you can shoot indirect fire into unspotted bridge hexes. A bridge hex is any hex containing a road and a stream or river. If you fire into an unspotted / unseen hex, you won't see the usual reports of damage to enemy units. The combat is still resolved normally, but results are hidden from view. FIRE : GENERAL Change: A unit's effective rate of fire on any given turn is now equal to it's nominal rate of fire. Ammunition allowing, units will fire a number of shots exactly equal to the nominal rate of fire of the slowest rate of fire weapon assigned to the unit. Random rate of fire checks have been removed from the game. Frantic fire (see below) may allow a unit to exceed it's nominal rate of fire. SMOKE FIRE Addition: The program won't allow you to order smoke fire into a hex that already contains smoke. AMMUNITION Addition: Most units will eventually run low on ammo if they fire their weapons. Infantry and artillery units with transports (trucks or whatever) will be less likely to run low on ammo as long as the transports are not destroyed. SCENARIO ENVIRONMENTAL EFFECTS Change: Weather is variable. Wind strength and direction, and precipitation can vary from turn to turn. If there is any precipitation, there is a chance that the ground condition will become "soft". Addition: Wind has the following effects: If there is no wind, smoke can be created during combat and it will tend to linger in the smoked hex for several turns. If winds are light, smoke can be created during combat and it will tend to drift with the wind from turn to turn. If winds are strong, smoke will not be created. If the scenario is set in the arid tileset and there is no precipitation much of the map will be obscured by blowing sand. If the scenario is set in the frozen tileset much of the map will be obscured by blowing snow. Patterns of blowing sand and snow will change from turn to turn. BATTLEFIELD RESUPPLY Addition: Helicopter units are never eligible for battlefield resupply. Once they run out of ammo, they stay that way. MORALE Addition: As units take losses, move through non-road woods or town hexes, mine hexes, or retreat under fire, their parent formation may suffer a loss of morale. The chance and severity of the morale loss is dependent on the whether any equipment is actually lost in the event, and how large a portion of the formation is involved. Helicopter equipped units will not suffer morale checks due to moving through closed terrain. Each turn, formations will recover morale. Reorganizing formations will recover slightly faster than those available for orders. The rate of morale recovery is dependent upon the standard national morale of the formation (see Appendix H for national morale values), so forces belonging to nationalities with good standard morale levels will recover from morale loss more quickly than those belonging to national forces with poor standard morale levels. PANIC UNDER FIRE Addition: When a unit takes a loss, it must pass a morale check in order to stay in place. If the unit fails the check, it will retreat one hex if possible, and will not return fire regardless of fire orders. Units which survive retreats may, depending upon a morale check, turn to face the hex they originally occupied. A unit with "hold fire" orders must also pass a morale check or it will panic and change its orders to "auto fire" if it takes a loss. Units belonging to formations with poor morale and control levels have a poor chance of passing morale checks. Units belonging to formations with good morale and control levels have a good chance of passing morale checks. FRANTIC FIRE Addition: Frantic fire is a special case of auto-fire. Under certain circumstances, units with auto-fire orders are allowed to fire at enemy units even if they have already moved or fired their weapons. Frantic fire lifts the normal limits on the number of shots that a unit can fire in one turn. There are two cases in which a unit may be allowed to franticly fire at enemy units: 1) Whenever a unit takes a loss, does not retreat, and passes a morale check, it will be allowed frantic fire. 2) If an enemy unit moves or fires in any hex adjacent to the unit, there is a 30% chance that the unit will be allowed frantic fire. HIDDEN UNITS Change: The list of units which can begin the game "hidden" has been considerably expanded. Almost all units equipped with direct fire weapons (other than ATGM's) and not equipped with transport are now eligible to be hidden. This does not affect units in scenarios created prior to the availability of version 1.25. Units now lose their hidden status if any unit in their hex changes facing. Hidden units will not "dig in". REINFORCEMENTS Change: Reinforcement entry turns are variable. On each turn that a scheduled reinforcement formation is off map, there is a small chance that the entry turn will either advance or be pushed back by one turn. You can monitor the current projected entry turn from the "Info:Formations" menu item. SCENARIOS: END OF SCENARIO Change: All scenarios are of variable length. There is a 50% chance that a scenario will be continued for at least one turn rather than ending on the nominal final turn of the scenario. This check is made at the end of each turn, so it is impossible to predict exactly when any particular scenario will end. If a scenario ends due to reaching its final turn, you can choose to override the end of the engagement. It is possible to extend the scenario to a maximum of 255 turns. This will almost certainly invalidate the scenario victory conditions, so you should take the scenario results with a grain of salt if you extend the game. CAMPAIGNS Addition: Whenever you start a new game without using the "Start next scenario in campaign" option, you are beginning a new campaign. Any old campaign will be lost. If you re-start a saved game from any file other than CAMPAIGN, any current campaign may be lost. The CAMPAIGN file contains the latest information on your campaign. Earlier saved games may not contain the information necessary to continue the campaign. Remember, the game automatically saves your game as file CAMPAIGN whenever you exit to DOS. You don't need to manually save games. Technical information: The campaign information is stored in the files CAMPAIGN.SAV, LASTGAME.DAT and CAMPAIGN.DAT in the scenario directory. If you want to permanently save a campaign, or send it to a friend, just copy these three files. To restore the campaign, re copy these files into the scenario directory. LASTGAME.DAT will only be present if you are between games in the campaign. EDITOR-DRAWING THE MAP Clarification: When you use the auto-fill tool, it will fill the map until a boundary of the same general type of tile is reached. If you don't draw a complete (no gaps) outline using the fill tile type before using the auto-fill tool, you may fill the entire map with the fill tile. Boundaries of other tile types will have no limiting effect on auto-fill. EDITOR-CREATE THE ORDER OF BATTLE Addition: As you create a formation with the order of battle editor, the program will create a formation name based on the types and numbers of units assigned to the formation. You can override the automatic formation name by clicking on the "Rename" button in the upper right corner of the current formation box. Your formation names are limited to 12 characters (11 for the tenth and subsequent formations). SCENARIO DESCRIPTIONS New rules section: A short scenario description may appear when you select a scenario for play. These scenario descriptions are stored in the form of small ASCII (text) files in the SCENARIO directory. If you wish to write a description for a scenario, you must follow these guidelines: 1) Use a text editor capable of saving text in ASCII form. The MS-DOS editor will do the job, as will most word processors. 2) A description can have a maximum of 14 lines. Each line can have no more than 36 characters. If you violate these limits, you may see strange results in your file description within the game. 3) The name of your description file must be based on the name of the scenario you wish to describe. If your scenario is named "MYGAME.SCE", your description must be named "MYGAME.TXT". 4) Your description file must be in the SCENARIO directory. 5) A sample description file (SAMPLE.TXT) is included in the SCENARIO directory. This can be used as a template for your scenario description files. You can also examine any of the *.TXT files already in the directory, but please do not modify them. APPENDIX B: EXAMPLES OF GRAPHIC DISPLAYS Addition to UNIT ICON: Static units have an additional "static" indicator graphic: a "dot" at center right on their icon, just below the "fire dot" location. VERSION 1.30 Due to time constraints, the rules changes for version 1.30 could not be incorporated in this document prior to its release. Please see the v1.30 version notes in HISTORY.TXT for details of the changes introduced in v1.30. RULEBOOK MISTAKES *Page 38, second bullet statement Delete "...that has slight, hidden effects for these values" There are NO "hidden" effects. *Page 41, Fixed Objective Values, last sentence. Replace "... using the manual objective value set button ..." with "... using the Objective Value button ...". *Page 43, Direct Fire Kill Probability vs. Armored Targets. The armor penetration calculation used in the game is actually a bit more sophisticated than that described in the rulebook. Replace "If the hit is...from one to five." (First sentence) with "If the hit is from a weapon with a hard attack rating, the target is killed if the hard attack rating of the firing weapon is greater than or equal to a random number from 0.75 times the armor rating of the target to 1.25 times the armor rating of the target. For example, a hit from a weapon with a hard attack rating of 15 would have the following chances to kill an enemy armored vehicle: Armor Chance 0...12 100% 13 78% 14 67% 15 56% 16 44% 17 36% 18 27% 19 18% 20 9% 21 8% 22... 0%" Appendix D - Equipment Description Table (Addition) Equipment Primary Weapon Secondary Weapon . . .

Special T-80 125mmATl HMG 37 9 22 NV SP WF SM Appendix H - Historical Forces (Addition) By popular demand, a new historical period has been added to the game database. Its all pretty self explanatory. The British, French, and Americans are similar to the forces used in 1991- with the inclusion of some older equipment not shipped to the Persian Gulf. The Russians and Ex-Pact can be used to create Russian civil war or Eastern European scenarios. Please note that due to memory limitations this extension to the database is pretty much limited to the equipment already included for other periods. Our intention was simply to provide additional flexibility to the game. But due to its late inclusion, the equipment mix in the "Tomorrow" database is not as complete as the mixes given for the earlier periods. 13. Tomorrow...
