I think the way to employ this monster would be the following..
when you pick the plane you list or ord to pick would include m-3/m-16 ow whatever vehicles you want. then when you land you could open the doors and then switch to your vehicle and roll on out leaving the plane out, then when you are finished raising hell you roll back in and close the doors and take off.
as far as it being easy to shoot down, here is what ya need to do for that. make its icon range the same as the flak panzer 1.5k
then FLY LOW! and if they dont see ya you make it, It would be a BLAST blobbing around 100 feet off the ground hideing from those scurvy sheister bastards!
ohh and what would 200 troops falling on a base look like?
do you think the acks could kill em all before they could capture?
