If practicable, exposed tracks are camouflaged by brushing out or covering with materials. Spoil and debris are covered or placed to blend with the surroundings. Camouflage construction must be maintained. Smoke from kitchen fires must be controlled and dispersed. Consequently the same standard of camouflage discipline must be adhered to by night as by day.
Light discipline is important at night.
Sound discipline is always important. Loud orders, talking, calling, coughing, and sneezing must be avoided. Hard ground should be avoided and full use made of soft ground. Signs should be used where possible. Tracks, debris, and equipment exposed in this bivouac area invite artillery and bombing attacks.
