This may have been suggested before, if it has then my apologies.
How about introducing a "perked" transport a/c that can land and disgorge a troop/or supplies loaded M3.
Maybe a C47 that tows a Glider, it would need two pilots with the Glider pilot then taking over the M3.
It may add something extra to game play, when a town is down the search is on for the troops, the M3 spawn point is normally capped and aircraft are looking for the C47, this is a method of creating a random M3 spawn point.
It's just a suggestion
