Fallout Tactics: Brotherhood of Steel Cheats

To avoid getting a penalty to your weapons skills and upgrading it instead while driving, set all your squad members to the prone posistion and make them crawl into the vehicle.

The first time you go to a random encounter, drop everything you can and leave. Then come back pick up all the stuff and leave again. Come back to the encounter and all the stuff you dropped will still be on the ground ready to be picked up again so now you have twice as much. Use as many times as you want no matter what you do the stuff will always be there. Only the stuff you dropped the first time you went there will reappear so dont come back and drop more stuff you'll just lose it.
