The D-442 FUG and D-944 PSZH are the results of Hungarian domestic development of relatively cheap amphibious armoured scout car and armored personnel carrier series. FUG and PSZH were exported with limited success, thus it is also known under its Czechoslovak designation OT-65.

The BRDM-1 is a Soviet amphibious armored scout car. It was the first purpose-built Soviet reconnaissance vehicle to enter service since the BA-64 and was built on the chassis and drive train of the BTR-40 armored personnel carrier. It is the world's first mass-produced combat vehicle of its class.
