Ok, lets say it would be a scuad composed of 8 terminator marines + 1 Librarian (psionic protection) + 1 apotecary. They are armed with 2 ATC's, 2 plasma guns, 2 rocket launchers and 2 laser guns (and i take the last ones for they are also used by the imperial guard). Of course, we do also have a couple of dreadnoughts (1 Hellfire + 1 Furious the first one to deal with BL's and the latter one for intermediate heavy fire support while the whirlwinds are the long one), a whirlwind and a Land Raider for transport. Now, set the aliens side. BTW Fomka, do not understimate space marines... trust me man... this guys are much stronger, much faster have much better power armors that X-Com operatives. Try to play Dawn of war or read the codex for better info. Edit: No, wait... let's say 2 Furiosos, 1 on the battlefield and the other one rdy to deepstrike.
