in rear has time to deploy before coming under effective fire." The
advance guard must be aggressive. Do not put up with a cautious point.
Have a double connecting file, and if possible every 100 yards. "Each
element of the column sends the necessary connecting files to its
front." On the road in order are: point--advance
party--support--reserve (if there is one)--main body. Have the point
precede the advance party, all the remaining elements follow the one
ahead. This has been found by experience to be the best method of
getting "there."

(k) _Rear Guards_.--"A rear guard is a detachment detached to protect
the main body from attack in the rear." "The general formation is that
of the advance guard reversed." i.e. rear point, rear party, support,
and main body. "In retreat a column is preceded by a body of troops
designated 'leading troops,' whose principle duty is to clear the road
of obstacles and to facilitate the withdrawal of the command."

(l) _Flank Guards_.--As their name imply protect the flanks. They
should be in constant communication with the column. Their formation
usually conforms to that of patrols.

(m) _Camps_.--The four principal factors to be considered in the
selection of the camp site are: near a good road or roads, have good
drainage, plenty of room to accommodate your troops, and have a good
water supply. Immediately after camp is made sinks are dug for the
disposal of excreta. One should be dug for each company on the
opposite flank from the kitchen for the disposal of human excreta, and
one near the kitchen for the disposal of wastes, etc., that cannot be
burned around the kitchen.
