The WW2 USA Half track had been converted into an sp morter carrrier called the M4
The mortar was an 81mm and fired to the rear and it was based on the shorter bodied M2.
The M21 had the same mortar fitted but the internal arangement was changed and the mortar fired forwards.
The display model has been enhanced with crew and stowage not included in the conversion kit.
Whilst we aim to make the conversion kits gamer friendly we have devised a skill rating to help you.
This kit skill level is B
72 scale conversion kit skill ratings:-
A = easy to assemble or simple add on parts
B = slightly harder to assemble a bit more time/skill needed.
C = harder to assemble with more fiddly parts and time need to complete
