Logical line of operation

From Wikipedia, the free encyclopedia

A logical line of operation (LLO) is an American military concept related to counter-insurgency doctrine. In the traditional sense, a line of operations is "an imaginary line between the force's base of operations and the objective.^[1]" In contrast, a logical line of operations is one in which "positional reference to enemy forces has little relevance.^[2]" In essence, an LLO is a strategy or a series of steps to address a problem, either military or non-military, within the context of counter-insurgency. Such problems may include traditional military objectives such as providing security or training host-nation security forces, or they may be unconventional tasks such as providing social services and economic development. The current U.S. counter-insurgency field manual identifies five different LLOs.

Combat Operations/Civil Security Operations
Host Nation Security Forces
Essential Services
Governance
Economic Development

Depending on their appropriateness to the situation, all five should be pursued simultaneously in order to weaken the root causes of insurgency. As many of these tasks exceed the traditional scope of the U.S. military, this concept is tied to the use of Provincial Reconstruction Teams (civilian reconstruction experts embedded with combat troops).
