The Joint Light Tactical Vehicle (JLTV), known and marketed under Oshkosh development as the L-ATV (Light Combat Tactical All-Terrain Vehicle), is a light utility/combat multi-role vehicle. The Oshkosh-developed JLTV was selected for acquisition under the US military's Army-led Joint Light Tactical Vehicle program. In the very early stages of the program it was suggested that JLTV would replace the AM General High Mobility Multi-purpose Wheeled Vehicle (HMMWV) on a one-for-one basis. It is now suggested that the JLTV will partly replace the HMMWV, not replace it.^[5]

The L-ATV was designed to deliver a level of protection comparable to that of heavier and less maneuverable Mine Resistant Ambush Protected (MRAP) class designs, these having more protection from blast than up-armored HMMWVs which they were delivered to replace on deployed operations.^[5]

In August 2015, the L-ATV was selected as the winner of the JLTV program.^[6] The first JLTV delivery order was placed in March 2016 with the U.S. Army ordering 657 examples.^[7] Overall requirements have fluctuated, but as of January 2022^[update] were stated by Micheal Sprang, JLTV Project Director to be: Army – 49,099 (this figure has remained relatively constant); Marine Corps – 12,500 (approx.); Air Force – 2000 (dependent on funding); Navy (approx. 400).^[5]

The JLTV achieved initial operating capability in the U.S. Marine Corps in 2019. The Army recompeted the right to manufacture the JLTV beginning with the A2 variant. In 2023, the Army selected AM General. Oshkosh expects to produce JLTVs into early 2025 and retains the right to produce JLTVs for direct commercial sale.
