A M113 APC called "Bottom Feeder" appears in the campaign level "The Defector" with a mounted M2 Browning Machine Gun. Also, during the beginning of the level "S.O.G.", Mason, Hudson, and Woods pass by multiple M113s while riding in a Jeep through the military base at Khe Sanh when the NVA and Viet Cong attacked. In the trenches, one can see several M113s in the trenches above. The gunners in them can be killed, but the .50 cal machine gun will continue firing. Later in the game, a damaged M113, named "The Outcasts," falls over a trench blocking Mason's path, forcing the player to go prone and crawl under it.
If the player shoots one of the gunners on the APC, the .50 cal will continue firing in the whole campaign.
The gunner on "Bottom Feeder" is not a solid character. As such, the player can walk through him.
It's possible to jump onto "Bottom Feeder" from the area where the player receives the radio. To do this, the player must time the jump exactly when Bottom Feeder drives underneath the position.
