Warlords, one at a time, because they are all pretty different. Shanxi (Yan Xishan) first.
Yan Xishan (II Military Region, II War Zone)
Shanxi & Suiyuan, N. Shaanxi, Chahar (technically assigned, but obviously not operational)
Shanxi (Yan, II War Zone) forces constituted 8 Army HQs, each nominally comprising 3 infantry divisions and associated Army-level troops. Initially organized with one field and 12 mountain artillery regiments, equipped from local production of the Taiyuan Arsenal, Shanxi forces lost much of their equipment in the 1937-38 fighting. As of January, 1942, the remaining pieces were concentrated in 4 ‘line’ artillery regiments of reasonably similar make-up, and a ‘training/reserve’ regiment holding what medium pieces remained.
The 23rd Regiment comprised 3 battalions; the 1st with 12 type-13 (Taiyuan copy of IJ Type-41 75mm Mtn) mountain guns, the 2nd with 12 type-17 (Taiyuan ‘improved’ type-13) 75mm mountain guns, the 3rd with 8 type-18 (Taiyuan licensed copy of Krupp 8.8cm FK Z.A.) field guns.
The 24th Regiment comprised 3 battalions; the 1st and 2nd each with 12 type-13 75mm mountain guns, the 3rd with 8 type-17 75mm mountain guns.
The 27th and 28th Regiments identically comprised 3 battalions; each battalion with 12 type-13 75mm mountain guns.
The training/reserve Regiment comprised one 3-battery (9 guns) battalion of type-16 (Taiyuan license built Krupp 105mm L/12 B.H.) mountain howitzers, and one 2-battery (8 guns) battalion of type-13 75mm mountain guns.
Shanxi forces’ organization, as of January 1942, held constant to the end of the Japanese war. The Jan. 1942 organization is identical to that of Oct. 1944. The following is only the organized ‘field’ force, itself nominally part of the National Army. It does not include ‘provincial’ forces, which were semi-organized militia-type levies formed into 3 ‘defense’ brigades.
6th Group Army – 19th Army (68th, T 37th, T 42nd Divs), 23rd Army (T 40th, T 46th T 47th Divs), 24th Arty Regt.
7th Group Army – 33rd Army (71st, T 38th, T 41st Divs), 34th Army (73rd, T 44th, T 45th Divs), 23rd Arty Regt.
8th Group Army – 43rd Army (70th, T39th, T 43rd Divs), 61st Army (69th, 72nd, T 48th Divs), 27th Arty Regt.
13th Group Army – 83rd Army (66th, T 49th, T 50th Divs), 1st ‘Cav” Army (1st, 2nd, 4th ‘Cav” Divs) 28th Arty Regt. (Cavalry in ‘name’ only, for historical/nostalgic purposes. Organized and equipped as ordinary Infantry.)
Average divisional strength (1944) was 6,711 out of an authorized establishment of 7,502, indicating they were well recruited. The Military Affairs Council (MAC) contributed a Field Army (the 13th) and an independent division (the 21st) to II War Zone. These were the only troops actually answerable to the central government, although the Shanxi forces were well regarded and considered loyal to Chonqing.
