higher armour
Yes, everything bounces off M10 didn't you know?
higher penetration
I guess I've seen puma shots bounce off soviet heavies occasionally
armour piercing rounds
Is this supposedly an advantage over Aimed Shot or Target Weak Point?
Puma also has better sight range.
So basically all of the M10's advantages are not really advantages at all because they make absolutely no difference whereas the puma's advantages are extremely powerful.
