There's something to be said for the XM1, the M1, the M1IP, the M1A1, the M1A1HA, the M1A1HC, the M1A1D, the M1A1 AIM v.1, the M1A1 AIM v.2, the M1A1 FEP, the M1A1 AIDATS, the M1A2, the M1A2 SEP, the M1A2 SEPv2, the M1A2 SEPv3, the M1E3, and all the changes that didn't get separate designations like the interim external APU or the TUSK kit.
It's confusing, but it's honest.
