What are P and D times? Why these are important to logistics strategy? Exlain Solution Logistics is a relatively new word used to describe a very old practice: the supply, movement and maintenance of an armed force both in peacetime and under operational conditions. Most soldiers have an appreciation of the impact logistics can have on operational readiness. Logistic considerations are generally built in to battle plans at an early stage, for without logistics, the tanks, armoured personnel carriers, artillery pieces, helicopters and aircraft are just numbers on a Table of Organisation and Equipment. Unfortunately, it often seems that the high profile weapon systems have had greater priority in resources than the means to support them in the field, be it ammunition, fuel or spares. For it is logistics that will determine the forces that can be delivered to the theatre of operations, what forces can be supported once there, and what will then be the tempo of operations. Logistics is not only about the supply of mat.
