I'm saying even a light mortar team loaded down with a reasonable amount will only have a few minutes of sustained fire capability. 1kg bomb * 20 rnds * 3 men / 20rpm = 3 mins fire effect. It's why they were particularly a stupid weapon that was phased out of most armies. Not to mention their cost inefficiency compared to artillery. Although I really like them for modern mechanized infantry usage. If a WinSP turn is supposed to be 2 minutes and I believe the 50/60mm mortars carry 80 "shots" which should represent rates of sustained fire / 4 shots per turn (excuse errors been a while since I played). That represents 20 minutes of effective fire or 400kg of ammunition between 3 or 4 men. Pretty goofy numbers.
It's also a major reality break problem with Moylan's Combat Mission series. Mortars and cannon on a foot advance have very limited capability.
