The full name of a personnel carrier is "armored transport vehicle", which is a tactical vehicle with armored protection in land warfare. Its core function is to quickly transport infantry and weapons and ammunition, and provide basic firepower cover and battlefield mobility support. The core difference between it and infantry fighting vehicles is that its firepower is weaker (mainly machine guns/small caliber artillery), its protection focuses on defending against light weapons and fragments, and its passenger compartment design is centered on transportation, making it inconvenient for combat on board. As a landmark equipment of army mechanization, its equipment scale was once an important indicator for measuring the modernization level of the military.
