The rear facing seat in the 'special' Land Rovers moves on the model depending on how far away from the vehicle you are viewing it from.
Starts off on the left of the vehicle when up close:

Walk further away and it switches to the right side of the vehicle:

Happens on both the M2 and the GMG armed Land Rovers in both camo schemes.
