U.S. Soldiers assigned to Able Battery, 3rd Battalion, 321st Field Artillery Regiment, 18th Field Artillery Brigade, XVIII Airborne Corps, instruct Estonian soldiers on M142 High-Mobility Artillery Rocket System (HIMARS) drivers training and vehicle maintenance at Camp Tapa, Estonia, April 26, 2025. In 2022, the U.S. State Department approved HIMARS sales to Estonia, which are now en route to be received. Their arrival will give Estonia precise long-range artillery capabilities to strike deep behind enemy lines. (U.S. Army Video by Pfc. Jaidyn Moore)
