This mod ports in the FBI Light Shotgunner model for the Federale Light Shotgunner, and modifies the Federale Light's texture to have the extra parts necessary for this shotgunner to display properly (shoulderpad for the strap holding the shells around his sholder, and the shells themselves)
This is unfortunately incompatible with retextures, unless they are of a similar layout (aka, the same layout as the FBI light or SWAT light texture, GenSec and similar will not work due to their differently-shaped, rectangular badges)
