Computation of Security Force Requirements.
a. The degree of security achieved will depend upon the efficiency of its
security force. However, seldom will any post have enough manpower. It can seldom
provide all the people desired.
It is very important, then, that the most
economical and efficient use be made of the force. This can be done only by well-
planned, accurate programming.
Annual man-hour commitments must be carefully
Also, individual performance must be determined.
These two acts must
occur before reliable manpower needs can be forecast.
b. Annual commitments for posts and patrols are expressed in terms of man-
hours per year.
To operate a post or patrol which is active the same number of
hours each day, man-hours per year required must be obtained. This figure is found
by first multiplying the number of men required times the number of hours the post
is operated per day. Next, multiply that figure by the number of days per week.
Then multiply that answer by the number of weeks per year.
Man-hours per year
equals the number of men; that is multiplied by the hours per day; that figure is
multiplied by days per week; the last figure is multiplied by weeks per year.
Computation examples are listed below.
Post #1 requires 2 men, is operated 24 hours per day, 7 days each
Man-hours per year -2 (men) x 24 (hours per day) x 7 (days per
week) x 52 (weeks per year) = 17,472
Post #2 requires 1 man, 16 hours per day, 5 days each week.
Man-hours per year -1 x 16 x 5 x 52 = 4,160
c. Some posts or patrols may be required only on normal operational days.
Others may be required at all times when the installation is non-operational. Post
#5 requires 1 man, 1600-0800, Monday through Friday, and 24 hours on Saturday and
Sunday. Man-hours per year:
Monday through Friday = 1 x 16 x 5 x 52 = 4,160
Saturday and Sunday = 1 x 24 x 2 x 52 = 2,496
Individual Security Force Performance.
a. The amount of work which can be expected from each person may vary. The
difference may be due to the person used or to the geographical location. It may
be due to climatic conditions and military situation.
