Theloss-of-strength gradient (LSG) is a military concept devised byKenneth E. Boulding in his 1962 bookConflict and Defense: A General Theory. He argued the amount of a nation'smilitary power that could be brought to bear in any part of the world depended on geographic distance. The loss of strength gradient demonstrated graphically that, the further away the target of aggression, the less strength could be made available. It also showed how this loss of strength could be ameliorated by forward positions.[1]
Boulding also argued that the loss-of-strength gradient was becoming less relevant in modern warfare due to easier transportation and the rise of strategicair andmissile power. He claimed that a 20th-century "military revolution" allowed for a "substantial diminution in the cost of transportation of organized violence of all kinds, especially of organized armed forces", as well as "an enormous increase in the range of the deadly projectile."[2]
On the other hand, another scholar contended that the loss-of-strength gradient continues to be relevant, and if there has been a reduction in the concept's significance, it was only temporary, as transportation is not becoming permanently easy, and air power is not replacing the need for forward deployed ground forces.[3]
