This is what I use for my Custom Maps.
[General]
AmerParaDropInf=E1,E1,ENGINEER
AmerParaDropNum=8,8,2
AllyParaDropInf=E1,E1,ENGINEER
AllyParaDropNum=6,6,2
SovParaDropInf=E2,E2,ENGINEER
SovParaDropNum=9,9,2
YuriParaDropInf=INIT,INIT,ENGINEER
YuriParaDropNum=6,6,2
This translates to:
America Para-Drop = 8 GI, 8 GI, 2 Engineer
Allied Para-Drop (Captured Airfield) = 6 GI, 6 GI, 2 Engineer
Soviet Para-Drop (Captured Airfield) = 9 Conscript, 9 Conscript, 2 Engineer
Yuri Para-Drop (Captured Airfield) = 6 Initiate, 6 Initiate, 2 Engineer
With respect, what I use is powerful enough assuming all 3 Planes make it to the Drop-Zone.
I would highly recommend not using things like Tier 2 and Tier 3 Units, especially since the game has to guess where the Chute is.
It can look scruffy on abnormally larger units sometimes.
If you insist on using those units, then I will provide the ID's of them (Listed bellow in order that you wrote in your message).
GHOST, SNIPE, SPY
DESO, TERROR
PTROOP, BRUTE
Comment: "MAD TANK DEPLOYED"
Multiple Commas equals more Planes.
So if I want 5 Planes, I would put something like:
[General]
AmerParaDropInf=E1,E1,E1,E1,ENGINEER
AmerParaDropNum=8,8,8,8,2
AllyParaDropInf=E1,E1,E1,E1,ENGINEER
AllyParaDropNum=6,6,6,6,2
SovParaDropInf=E2,E2,E2,E2,ENGINEER
SovParaDropNum=9,9,9,9,2
YuriParaDropInf=INIT,INIT,INIT,INIT,ENGINEER
YuriParaDropNum=6,6,6,6,2
Obviously, I wouldn't do this since most players wouldn't cope with that coming from the skies into their base.
Though taking down the Planes can be easy, if you have an 8 Player Map going 1 VS 7, and those 7 drop Para's on you...
Let's just say 3 Planes per Player is bad enough, 5 Planes 7 times would flatten your base (Debris alone).
I might actually try this just to see what it takes, and how much strain on CPU's this could create.
Hahahahahahaha, that sounds crazy as I'm writing it.
