"As part of the package, the Biden administration will provide Switchblade drones, according to people briefed on the plans. Military officials call the weapon, which is carried in a backpack, the “kamikaze drone” because it can be flown directly at a tank or a group of troops, and is destroyed when it hits the target and explodes.
“These were designed for U.S. Special Operations Command and are exactly the type of weapons systems that can have an immediate impact on the battlefield,” said Mick Mulroy, a former deputy assistant secretary of defense."
