Currently the Bobcat 3D model shows a 12.7mm HMG barrel but is only fitted with a 6.5mm LMG

The Bobcat's RWS should eiter have the 3d model gun barrel changed to depict a 6.5mm LMG (the weapon currently fitted to the vehicle in the config), or have the config changed to a 12.7mm HMG (the same sort used by the Hunter HMG in an identical RWS). The ammo boxes fitted on the hull are also 12.7mm boxes.

Based on the rest of the NATO vehicles RWS being 12.7mm, I'd suggest that the vehicle's config is changed to a 12.7mm HMG. Contemporary US mechanised support vehicles of this type are almost always fitted with a HMG rather than a MMG/LMG so they can engage light armoured targets.
