The M15 anti-tank mine is the only available mine in the game, and used by both BluFor and OpFor (inaccurately) factions.
The M18 smoke grenade is used by BluFor factions, and available in white, red, green, yellow, orange, purple and blue colors.
The M67 hand grenade is used by BluFor factions, incorrectly by the British Army too, as the L109A1 would be more accurate.
The RGD-5 hand grenade is used by OpFor factions.
The SPG-9 recoilless rifle is used by ChKDZ and NAPA factions as a static weapon, or mounted on UAZ jeeps.
The ZU-23-2 is available either as a static mount or mounted on an Ural truck as a dual purpose anti-aircraft/anti-infantry weapon.
The Podnos 2B14 82mm mortar is the standard mortar of the Russian Federation faction.
The M252 mortar is the American equivalent of the Podnos 2B14, and functions similarly in-game.
