I remember one of my instructor in OETI telling us that 1 hit
from a 7.62 round will most likely kill but for a 5.56, you may
kil, you may not kill the fella, leaving the fella hit in agony and
pain.
Wounding more enemies have a greater pychological and logistical
impact than killing more enemies. as the cries and screams from
fallen comrades are demoralizing than dead comrades and the
logistics involved to evacuate and care for the wounded will put a
bigger strain on the enemy.
This may sound cruel but which war isn't. And believe it or not,
this is also one of the reasons (never officially acknowledged) the
US chose the 5.56 over the 7.62.
Depends on 7.62 fired from what. 7.62 shot from an GPMG
would probably take limb clean off. But a 7.62 from an AK
might not be as wounding as you think. Its about the muzzle
velocity if i am not wrong.
