But Battlefield 2 damage system, just meh.
M16 requires 4 body shots vs regular people, 5 shots vs ppl with body armour.
The AK101, which uses the same caliber, only needs 3 vs regular ppl!
Keep in mind, that there is a huge diffrence between the 5.45x39mm and the 5.56x45 NATO round
The 5.45x39 had a slightly shorter range, but damage wise, it is far deadlier then the 5.56
There is a tiny hole at the tip of the bullet, once the round hits a target, the bullet tilts vertically and has an unusual, but damaging pattern of causing flesh trauma. that way, causing a much huger wound then with a 5.56mm nato round
NATO doesnt use such a round, because it is forbidden.
