In Battlefield: Bad Company's singleplayer, it appears on certain missions such as Crossing Over, Crash and Grab and Ghost Town. When the player uses it on Crossing Over and Ghost Town, the player's squad will man the mounted weapons, and there will be someone hanging on the back as a passenger.
In multiplayer, the CAV appears on the Gold Rush modes of Oasis, Final Ignition, Deconstruction and Harvest Day. It also appears on the Conquest modes for Harvest Day, Par for the Course and [information needed].
In Battlefield: Bad Company 2's singleplayer, on the scripted moment of the truck chase on Cold War, the car chase in Crack the Sky and as a primary transport for the larger portion of Sangre Del Toro.
In Multiplayer, the CAV appears on the Onslaught version of Nelson Bay. It spawns under the control of the Russians at the final base, but can be easily destroyed/taken over by killing the XM307 gunner on the back. The CAV also appears on Port Valdez on Conquest mode, spawning regularly at both deployments. It also appears in Heavy Metal and Harvest day.
The CAV is initially under enemy control, but it will pull up to the side of the Submarine Base's communications center where the diver will exit the vehicle an only the gunner manning the XM307 will remain, where he can be easily killed. Once the enemy is disposed of, the players can use the CAV for themselves. Once the base has been ridden of initial enemies and the flag can be captured, the players can position the CAV on the road to face the enemy spawn points and use to their own advantage as a turret. It would only require one player to stay in the CAV as the other three capture the flag and it can be a sure-fire way of completing the final segment of the map, even on harder difficulties, especially if the player in the CAV can kill the enemies before they can get a shot of themselves.
