The Growler ITV is a vehicle that appears in Battlefield 3. In the Single Player campaign, the vehicle is seen as part of the USMC convoy in Rock and a Hard Place, and is unusable by the player.
In Multiplayer mode, it is the US equivalent to the Russian VDV Buggy. The vehicle can transport up to 3 players; - a driver who controls the Growler, a gunner who operates the mounted 50. Cal and a passenger who can use their infantry weapons while in the vehicle. The vehicle is resistant to small arms fire, but passengers are very exposed to fire through the windscreen, open cab and rear. The vehicle can be disabled by simply throwing a M67 or 40mm Grenade into the vehicle, usually killing its occupants or can be disabled with one shot with an RPG-7,SMAW or FGM-148 Javelin.

The M1161 ITV is the American counterpart to the Chinese LYT2021 and Russian VDV Buggy It functions similarly to its previous appearance in Battlefield 3. It features 3 seats: 1 driver, 1 gunner, who operates an M2 machine gun, and 1 passenger, who is free to use their own equipment. The M1161 ITV is an unarmored transport, unlike the MRAP.

- The Growler and VDV Buggy now have a car horn after a patch.
- There are five seats in the Growler, as can be seen in Rock and a Hard Place, yet in Multiplayer there are only three seats available.
