The U.S. is preparing to send Ukraine an additional $725 million in military assistance, including counter-drone systems and munitions for its High Mobility Artillery Rocket System, which could indicate more of the longer-range missiles are headed to the battlefield.

Two U.S. officials did not confirm whether the munitions for the HIMARS are the coveted ATACMS — the Army Tactical Missile System — but Ukraine has been pressing for more of the longer-range missiles to strike additional targets inside Russia.
