There's two version because one of them dont work on MP dedicated servers.
(Ultimate Soldier 2) works only on SP/COOP server no MP dedicated server support, and is aimed of sp/coop matches only.
(Ultimate Soldier 2 MP) has MP dedicated server support and works on servers and dont change the fatigue effects over npc in your squad ( to avoid conflicts ), and has CBA dependency.
The old version of the mod ( Ultimate Soldier 1.00) works on SP/COOP/MP matches but with the latest game updates some parts of the mod dont work properly that's why I created to separate versions of the same mod.
