First Presidency letter "TO PRESIDENTS OF STAKES and BISHOPS OF WARDS . . . Where the military regulations are of a character that 'hinders', that is, makes impossible the wearing of the regulation garments, either in training on the drill grounds or in combat zones, effort should be made to wear underclothing that will approach as near as may be the normal garment. Where military regulations require the wearing of two-piece underwear, such underwear should be properly marked, as if the articles were of the normal pattern. If circumstances are such that different underwear may be turned back to the wearer from that which he sends to the laundry, then the marks should be placed on small pieces of cloth and sewed upon the underwear while being worn, then removed when the underwear is sent to the laundry, and resewed upon the underwear returned."
