=96. Signals used between firing line and reserve or commander in rear.= (1) For communication between the firing line and the reserve or commander in the rear, the subjoined signals (Signal Corps codes) are prescribed and should be memorized. In transmission, their concealment from the enemy's view should be insured. In the absence of signal flags, the headdress or other substitute may be used. (See par. 863 for the semaphore code and par. 861 for the General Service, or International Morse Code.)
