Should a 120mm mortar be towed by a prime mover?

Hey Peter,

I think you are correct. 

My old Mortar Platoon Sergeant came up with this note:  

This Soviet-era muzzle-loading mortar could easily broken down into three parts – barrel, bipod and baseplate – for movement over short distances or towed by a GAZ-66 truck on a two-wheeled, tubular carriage. The baseplate mounting permits all-azimuth firing, however as with most Soviet mortars it was difficult to turn rapidly over a wide traverse. It could accommodate small-angle shifts of up to 6 degrees without having to shift the baseplate though.
