Would be killed by a spit I without the blockhouses.
And how do you propose we move them? Shall we have the crew haul them around at 25mph while the ammo is magicly transported at the same time? That would be way too gamey. Could see it if they moved at 5mph, and had to be "supplyed" by an M3 every time they moved more than 200yds.
And it wouldn't stop campers any better than a tank (worse in fact, they have no armor, so .30's will be instant kills).
Wouldn't mind if we could have an M3 hitch one and tow it to where it wants to go, and then let it possition itself (get under the trees, or turn it the right direction) after the M3 has unhitched the gun. This would be usefull on the maps with canyon GV bases. Haul a few out when you're getting your bellybutton kicked and retreat past them so the attackers run into a pit trap(metahporicly speaking). Since they are just the guns, they would be damned hard to see in tall grass (if you turn the detailed ground off, you don't see any of that stuff, so they could hide in the bushes (for the other guys) and kill them before they're spotted.
We could do that by taking the panzer's gun, mounting it on a historicly accurate carriage, and calling it a Pak-40. Infact, I'm going to make a new thread for this. Ty 321BAR.
