=95. Signal flags used to mark assembly point of company, etc.= In
addition to their use in visual signaling, these flags serve to mark
the assembly point of the company when disorganized by combat, and to
mark the location of the company in bivouac and elsewhere, when such
use is desirable. (46)

=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.) (47)
