Battlefront is showing off another unit for Fate of a Nation with a look at the BTR-50PK.
From the article:
This blister includes one BTR-50 transporter with .50cal AAMG (for Vietnam) and AAMG (for Arab Israeli)
The BTR 50PK is a Soviet amphibious armoured personnel carrier based off of the PT-76. Unlike other BTR models the BTR-50PK is tracked instead of wheeled. The transport itself can carry up to twenty fully equipped men.
