that's interesting, strategy wiki places the G36's damage at exactly 33, so it would be a 4hit with 1 HP left over, perhaps that site tested at mid range.
a few things are messed up in that chart too, the MP5 kills in 4, M4 and SCAR are 4 only at point blank, and the mac10 is actually a 4shot
and what are the chances of all 3 shots from an AK or Mk48 landing in a row?
