介紹BMP-3的資料(註7)： 「Object 688(BMP-3的原型車)是採用Object 685(替代PT-76的輕戰車)的底盤， 導致乘員下車不便，但適合做為兩棲步兵戰車。」 原文： 「The Object 688 prototype created in Kurganmashzavod used a hull adapted from the Object 685 amphibious light tank, which resulted in less than optimal provisions for passenger dismounting, but otherwise had excellent potential as an amphibious troop carrier.」
BMP-3砲塔高度540毫米，等於0.54米(引用前面註解的網站，註7)： 「The turret has a low height of only 540mm and a width of 2,266mm, making it a relatively small target when a BMP-3 is in a hull-down position.」
