the bad thing about wire is that a grenade or a vehicle running through it will destroy it. around sniper blitz wave (lvl 70 or so) tanks will come in all the time (or other vehicles) and you'll just lose money
good strategy: place 4 jeeps near the top of the map (german's won't throw grenades that close to their lines, and enemy artilery never targets there) than build a bunker with 2 gunners inside. finally put a tommy gunner, and a few shotgunners, and you should survive like me to wave 140
wave 87 had a great defence spread out in middle and top of map (to avoid grenades) with frenchies grouped at bottom to attract artillery. all it took was arty blitz wave, an a bomb to finish me off. WTF! they launched like 20 arty shells at me
medics carried around a light handgun (pistol) for self defence only. apparently they don't use it for self defence in this game, they just lie down and hope the enemy misses
