"October 2, 1966 - Despite fighting for the liberation of their people, the Viet Cong were notorious for using questionable tactics. The V.C. would use strong arm tactics to manipulate villagers in the south in order to further their cause. Operation Irving was a combined operation meant to locate and eradicate Viet Cong pockets in the villages of the south."
Operation Irving is an Assault map. The US forces begin with a constant ticket loss. This loss can be stopped by neutralizing and/or capturing an enemy control point. The Viet Cong forces begin with four control points. The Viet Cong will begin to constantly lose tickets if all but one control point is captured.
All flags in this map are capturable. The US team has one large base with helicopter pads, a PBR dock and an airstrip, far from the VC flags. While helicopters and boats provide fast transportation between the US base and the battle arena, the US base is accessible by foot.
Much of the map, especially the school center, is a visual reference to the film Apocalypse Now, where a group of American Huey helicopters attack a Viet Cong village while playing Richard Wagner's Ride of the Valkyries, which looks extremely similar to the one in this map (in which two gunship Hueys and one transport Huey is available, the PBR is also available in the US base in singleplayer).
