Description
The M-10 was much more advanced design compared to older Soviet 152 mm howitzers. It had modern split trail carriage, which allowed for much larger traverse. The trails were of riveted construction. The carriage was equipped with suspension and with wheels from the ZiS-5 truck, meaning higher transportation speed.
The barrel, much longer than that of older designs, was fitted with interrupted screw breechblock with recoil devices consisting of hydraulic recoil buffer and hydropneumatic recuperator. The recoil length was variable. Gun shield provided the crew with limited protection from bullets and shell fragments.
Unlike its eventual successor, the D-1, the M-10 was not equipped with muzzle brake. While softening a recoil and thus allowing lighter carrige, muzzle brake has a disadvantage of redirecting some of the gases that escape the barrel toward the ground where they raise dust, revealing the gun position.
The gun could be towed by an artillery tractor or by a horse team. In the latter case, a 400-kg limber was used.
