- No, but they working on it. It kinda the same as radios, not
- every truck and jeep has got one, not every guy in a platoon
- has got one, so I doubt if everything/one will get a GPS.

- The computer on your desk may be able to do it in ".5 nano-seconds"
- but I can guarantee you that no tactical computer system can. The
- standard for time-to-release from pilot-trigger is like 50 - 100
- milliseconds. And it's hard to even make that sometimes. There's
- a weapon system out there that has a time-to-fire time of 100 msec
- + or - 500 msec. That's right - you pull the trigger and the damn
- thing may "leave" anywhere from 100 to 600 msec later! That's over
- a half second delay!
-
- The military is usually about 5 years behind in computer technology.
- It sometimes takes years of testing before they even let a piece
- of equipment "fly". If you wanted to put a 486/50 on an F-16, it
- would be at least a year of testing before it went wheels-up!
