The artillery support of a NK and
CCF division (about 11,000 strong) included
12-122mm howitzers, 24-76mm guns, and 12-SU 76mm
self propelled guns, plus anti-tank weapons. In
addition, the regiments and battalions had their
own supporting weapons.
Specifically addressing mortars,
each regiment had 6-120mm units. Each battalion
had 9-82mm mortars, and each company had their
own 61mm mortars. These mortars were the simple,
reliable Soviet types used by all their satellite
countries, and could fire the US 81mm and 60mm rounds.
The 120mm mortars were the
heaviest artillery used by the CCF attacking X
Corps in Chosin, with
the initial assaults by the CCF 124th division
supported by nothing heavier than their 82mm
mortars.
