Battlefield: Bad Company 2 Vietnam launching only as DLC

Battlefield: Bad Company 2 Vietnam will add four new multiplayer maps, as well as 15 new weapons and six vehicles, all congruous with the new 1960s locale and Bad Company 2's universal experience point system. Among other era-specific items, you'll gain access to the M79 grenade launcher, the Navy SEAL XM22 machine gun, the American Huey helicopter and the Russian T54 tank.
