I was thinking on commanders like "Lend and Lease" or "Soviet industry" followed by tactics.
I think the ability "supply drop" its kinda useless because you spend 100 ammo for a supply aircraft that comes from the enemy base, and if there's is a OBK with flak emplacement, or OST with Sdkfz 222, or a couple tanks with the mounted MG, your supply aircraft never comes to your base, losing 100 ammo on nothing (maybe there's a chance of lose the airdrop 40% on early and 80% on late game). German Factions have a ton of AA things to kill planes.
Sooo I propose the following changes (just one):
1-Supply aircraft coming from the sides, not from the enemy base, so there's a big chance of obtain the supply crates,
2-Reducing the cost from 100 to 80 or 60.
3-Coming from enemy base but giving the player supply crates with 40 fuel.
