From: In a van, down by the river.
In long campaigns, I typically buy 2 cargo planes and a glider to use in my Assault/Advance missions.
Love the effect, and I've been using a variant of your tactic for a while now.
Remember to look at the carry capicity of your cargo planes. The DFS 230 can carry 110 IRRC. That means it could do a 50mm AT gun and 2 PzShreck teams ;).
If you see a UK gilder, be VERY wary. Reason being, the Hamilcars could have light tanks! :eek:
One Tupelov could drop 5 X 12.7mm Dshk HMGs and 5 X SO Bazooka teams, or alternately 1 X Paratrooper Squad (12), 2 X 12.7mm Dshk, 2 X SO Bazooka, and 1 X Sapper Squad (6) - my personal favorite :D.
