The uniform classes of the vn_b_uniform_macv_04 variants have a different weight and load (6 lb vs 7lb) compared to their counterpart vn_b_uniform_macv_05.

The 04 Version is the rolled-up sleeves version.
The 05 Version is the rolled-down sleeves version.

Other then that, there are no changes to the models, yet the sleeves rolled up version somehow is 1lb lighter.
