@Read the Report
The report informs you of the present situation, showing scores, conquests and more important, which invasions and border incidents are in progress.
In combination with the maps showing battlefields and conquests you may easily find the desired information.
To find out how a nation has developped look at its history.

@Time and Distance
In planning an operation you must consider the time it takes to reach the target.
You must carefully plan each operation to assure that the right amount of material is in the right place at the right time.
Small borderlines and narrow passes may lead to time consuming invasions with heavy losses.
If you open a far-away-offensive overseas it is vital to conquer one or more nearby islands with cities for recovery, so as to keep your supply lines as short as possible.

@Reducing Losses
Instead of engaging in massive confrontation you may destroy enemy divisions one by one from across the border, retreating immediatly afterwards. You can accomplish this by pre-setting attack and retreat routes.
Make sure you have no activated divisions nearby because these will immediately start an invasion as soon as one of your divisions enters enemy territory.

@Using Squadrons
Divisions aboard squadron are invisible to other players and cannot be attacked.
Activated divisions will automatically try to land to participate in your ongoing battles.
Once a division has planned its route, its carrying squadron will wait for the division to land before proceeding its route.

@Sharing an Occupied Country
There may be several reasons to share an occupied country with other players:
* You conquered it together with others.
* You support an ally by "lending" cities temporarily.
* You let an ally station troops to discourage enemy invasions.
* You allow an ally to attack others from your territory.

@Communicating with Others
When you join a game you do not know which countries are being represented by whom.
By watching troop movements you may establish which countries are being played by humans.
It is vital to try and communicate with other players from the start.
Once you engage them it is important having them for allies or knowing them to be enemies.

@Intelligence
You have your own intelligence service residing at your capitol city, working for you around the clock even if you have been chased from you own country.
Not only does it keep you informed on all troop movements worldwide day and night, occasionally it even succeeds in intercepting messages to others!
