GMC DUKW Amphibious Transport
The "Duck" is an amphibious transport truck whose model name means: D:1942 U:utility K:all-wheel drive W:two powered rear axles
GMC is responsible for such model naming conventions.
The DUKW can traverse land and sea in an almost seamless fashion, unlike normal deployments or transport missions where trucks and boats must be used to traverse water areas, the DUKW can take infantry almost to any desired place in the map.
With the added capacity to set up a small supply radius, the Duck becomes a mighty good option when it comes to making landing assaults.
