Which warhead size is the most commonly produced APERS for RPG-7?

The most commonly produced anti-personnel (APERS) warhead size for the RPG-7 is 40mm. This size is effective for delivering explosive rounds designed to target infantry and light vehicles. The 40mm warhead balances manageable weight and compact size while providing sufficient lethality against personnel. Additionally, the RPG-7's design accommodates this warhead size well, making it a preferred choice in various military engagements.

Other sizes, such as 60mm, 80mm, or 100mm, are less commonly produced in the APERS role because they may offer more explosive power than necessary for anti-personnel purposes, making them more suitable for anti-armor or heavier targets. The 40mm warhead consistently meets operational needs for infantry support, keeping logistics efficient and effective in a variety of combat situations.
