On the other hand, the Chinese Reds broke with both Nationalist and Communist tradition in their policy of avoiding a permanent rank system. Officers (in Korea denoted by red piping on their sleeves) were divided into company, field, and general groups. The company commander and political officer held about equal authority in an infantry unit, and the only NCOs mentioned in CCF field reports are sergeants and squad leaders.[223] [223] ADVATIS FWD Rpt 0213 in EUSAK _WD_, 14 Nov 50; G-3 _SAR_, 21–22. _CCF Arms and Equipment_ The CCF depended on a wide assortment of weapons, so that it was not uncommon to find several different kinds of rifles of varying calibers in the same regiment. Japanese arms acquired after the surrender of 1945; Russian arms furnished by the Soviets; and American, German, Czech, British, and Canadian arms taken from the Chinese Nationalists--these were some of the diverse sources. And it is a tribute to the adaptability of the Chinese Reds that they managed to utilize such military hand-me-downs without disastrous confusion. Paper work was at a minimum in a force which kept few records and numbered a great many illiterates. As for logistics, each soldier was given a four-day food supply in the winter of 1950–1951 when he crossed the Yalu--usually rice, millet or soy beans carried in his pack. Afterwards, food was to be procured locally by extortion or confiscation, though the Communists were fond of using such euphemisms as “purchase” or “donation” to denote those processes.[224] [224] There is some evidence of an attempt to supply troops from division stocks. See ADVATIS 1245 in EUSAK _WD_, 4 Dec 50, and 164-MISDI-1176 in _Ibid._, 1 Nov 50. Normal CCF doctrine, however, held that a division should be committed to combat for about six days and then withdrawn to replenish its supplies and replace casualties. This procedure, naturally, definitely limited the extent of an attack by the CCF and prevented the maintenance of the momentum for an extended offensive. MajGen D. G. Barr testimony in _MacArthur Hearing_, 2650; Bowser Comments, 23 Apr 56. The CCF soldiers who fought in Korea during the winter of 1950–1951 wore a two-piece, reversible mustard-yellow and white uniform of quilted cotton and a heavy cotton cap with fur-lined ear flaps. Issued to the troops just before crossing the Yalu, the quilted cotton blouse and trousers were worn over the standard summer uniform and any other layers of clothing the soldier may have acquired. The first CCF units in action had canvas shoes with crepe rubber soles. Later arrivals were issued a half-leather shoe or even a full leather boot. Chinese footwear was of poor quality and few of the troops wore gloves in cold weather. The consequence was a high rate of frostbitten hands and feet.[225]
