Other U.S. Army development activities were largely focused on the potential for open warfare with the Soviets. Insurgents on the other had presented an almost completely different adversary, against which the full conventional power of the U.S. military could not always be directed.

At the time, the U.S. was steadily increasing its involvement in Southeast Asia, for instance. A number of insurgencies threatened U.S.-friendly governments in the region. As time went on, the LWL would become very much involved in development equipment for U.S. forces in Vietnam, where counter-insurgency was the name of the game.
