A D A M

Not really sure what section to ask this question but i digress, Are the full ghillies supposed to be a 1 shot kill no matter the gun and no matter where they are shot? I did some testing today and found that 1 Rook 9mm shot to the leg while wearing a full ghillie results in a 1 tap however any other clothing (even no clothing) results in a broken leg. I would just like to know if this is indeed bugged or intentional.
