BS!!!!!!
Elite:
The Spectre Gunship Crews are considered ELITE in the AF
Submariners are considered ELITE in the Navy
So, defining elite, or the criteria is important! Or at least the objective will determine the whole "eliteness" of the organization.
Are we going with prolonged ground combat?
Anything prolonged then we need to eliminate the SEALS, the Delta and others. As most are mission orientated and not trained or geared for long term operations.
SF, they can go bye bye! As their mission is counter insurgency and working with locals. Kinda like "The Peace Corps" but with guns
Snipers, eliminate, they are single mission orientated.
Any of the Air Force types GONE!!! Again specific mission objectives and they are not designed for combat.
If its get in and get out without engaging then some of the above units are good, if its get in and attack different storey. And then if its sustained attack or combat operations then its something else.
