I have a small suggestion for Obat 13 in general: add a new LBM for Unit 4. The LBMs in the current and revised USMC OOBs are quite generic whereas the POA-CWS-H5 had a very distinctive appearance. It may deserve its own LBM. If that is possible?
A POA-CWS-H5 of the Marine 1st Tank Bn. during the Korean War (March 1951):
The icon in the revised OOB is more accurate than the one in the current OOB. It shows a M4A3 (105) as it should. I don’t know whether the POA-CWS-H5 flame tube could be added to the turret or not?
