I'm not 100% sure what the scenario designer intended here. The Israelis used the Keshet ("Bow") mortar carrier variants of the M113, but I don't know if they specifically used the M1064 120mm mortar carrier. Since nobody makes that vehicle in this scale to my knowledge, the M106 or M125 mortar carriers will be as close as I can get. (The 'M65' is a reference to the model of mortar.)
