 For the first time, U.S. will provide armoured vehicle-launched bridges to Ukraine. The United States announced a new security assistance package for Ukraine, estimated at $400 million. This was announced by Secretary of State Antony Blinken. This military assistance package includes ammunition for Himmars and Howitzers used by Ukraine as well as ammunition for Bradley infantry fighting vehicles, pontoon crossings and maintenance and training. Blinken said, The armoured vehicle-launched bridges unfold to help tanks and other wheeled combat vehicles cross gaps and rivers in combat conditions. The bridge can typically unfold in about three minutes and stretch about 60 feet according to the Worldwide Equipment Guide. U.S. officials say the package includes eight of these bridge-launching vehicles. River crossings in a contested environment are considered risky maneuvers but will be critical to Ukraine's ability to make advances during its expected counteroffensive this spring. In addition to the bridges, the package supplies more ammunition for the Howitzers and the long-range rocket systems the U.S. has previously provided.
