For many reasons, chief among which is the difficulty of handling large units at night and maintaining contact, small units should be used.
199.—A battalion the maximum.
The fire of the adversary being negligible at night, there is seldom any advantage in putting more than a battalion in line against a given objective, the quality, discipline and cohesion of the troops making up for the number.
200.—Special precaution.
Before beginning the approach, carefully secure all arms and utensils so as to prevent noise. Fix bayonets.
201.—Method of advance.
Walk in double files on sides of roads, never in the center. Otherwise as long as practicable, in columns of squads.
202.—Liaison.
Commands are to be transmitted in a low voice by connecting files.
203.—To secure surprise.
