Sorry if this has been brought up before but in the US and USMC OOBs, the TOW-2A has different values for warhead size + HEAT Penetration Values. Are they different somehow or could it be a typo?
US - #158 Size 6, HEAT 80
USMC - #163 Size 8, HEAT 100
Also, in the Belgian OOB The TOW2 (#164) is weapon class 13 while in the Yank OOBs it is class 21.
