US Army soldiers fire High Mobility Artillery Rocket System HIMARS in Kuwait
US Army soldiers fire High Mobility Artillery Rocket System during an exercise near Camp Buehring in Kuwait on January 8, 2019. These powerful weapons have been game-changers in Ukraine.
  • Ukrainian troops usually won't fire their HIMARS without targeting data from the US, officials said.
  • The US-provided HIMARS have been a key weapon for Ukrainian forces throughout the war.
  • Ukraine has repeatedly asked for longer-range missiles to make the weapons more deadly.

The Ukrainian military almost never fires the US-provided High Mobility Artillery Rocket Systems (HIMARS) that have devastated Russian forces unless they receive targeting data from the US, The Washington Post reported, citing Ukrainian officials.
