Why? Cuz nobody did so I just built the first BTR-152 in simpleplanes (I did not see a single BTR -152 build in the community even when I searched for it). I could be wrong about being first but who knows.

INTRODUCTION:
The BTR-152 is a Soviet 6×6 armored personnel carrier introduced in 1949. Built on the chassis of the ZIS-151 truck, it carried up to 18 soldiers in its open-topped armored hull. While lightly protected, it provided mobility and basic protection for infantry units across the Warsaw Pact and beyond. The type saw many variants, including command, ambulance, and anti-aircraft versions, and was widely exported. By the late 1960s it was replaced by the BTR-60, but the BTR-152 remained in service with allied nations for decades.
