Light Infantry - Contemporary Light Infantry Forces

Contemporary Light Infantry Forces

Today the term "light" denotes, in the United States table of organization and equipment, units lacking heavy weapons and armor or with a reduced vehicle footprint. Light infantry units lack the lethality, tactical mobility and survivability of heavy units, but possess greater operational mobility and the ability to execute missions under restrictive terrain and weather that may otherwise impair a heavy unit's mobility. Light infantry forces typically rely on their ability to operate under restrictive conditions, surprise, violence of action, training, stealth, field craft, and fitness level of the individual soldier to address their reduced lethality. Ironically, forces in a light unit will normally carry heavier individual loads versus other forces; they must carry everything they require to fight, survive and win due to lack of vehicles. Although units like the 101st Airborne (Air Assault) and the 82nd Airborne Division are categorized as Air Assault Infantry and Airborne Infantry respectively, they fall under the overall concept of light infantry.

In the 1980s, the United States Army increased light forces to address contingencies and increased threats requiring a more deployable force able to operate in restrictive environments for limited periods. At its height, this included the 6th Infantry Division (light), 7th Infantry Division (light), 10th Mountain Division (light infantry), 25th Infantry Division, and the 75th Ranger Regiment. Operation Just Cause is often cited as proof of concept. Almost 30,000 U.S. Forces, mostly light, deployed to Panama within a 48 hour period to execute combat operations.

During the 1990s, the concept of purely light forces came under scrutiny due to their decreased lethality and survivability. This scrutiny has resulted in the Stryker Brigade Combat Team, a greater focus on task organized units (such as Marine Expeditionary Units) and a reduction of purely light forces.

Despite their reduction, light forces have proven successful in Afghanistan (Operation Enduring Freedom), underlining the continued need for light infantry.
