Mated please look at these 2 battle reports.
In the first he got 29 RPG kills while the only kit he has any score for is Assault. As well as 65 spotting ribbons.
In the second He / she also gets 22,212 points as assault but nothing to suggest he was playing this class, also played support that round again there is nothing to show this. No Ammo, Medikit, Defib Medals. But did get 113 MBT LAW kills but only 836 points as engineer. As well as 98 spotting ribbons.
Also looking through a later report for the player he went on to do the same on another locker servers.
