The Biden administration is reportedly about to supply the Ukrainian military with 100 units of the lightweight Switchblade missile system. The Switchblade is a baguette-sized bomb with a six-mile range and the US shipment will cost around £600 million. The missile setup can be carried in a backpack and unlike most missiles, does not need a target before being launched.
When the Switchblade missile is deployed it is capable of flying over enemy lines to identify and then hit battlefield command and control headquarters.
The lightweight weapon is controlled from a tablet computer and has increased the threat to high-profile Russian generals.
Since the conflict began seven Russian high ranking military figures are believed to have been killed by Ukrainian forces.
The Switchblade was used by US soldiers in Afghanistan and Iraq.

But, the 20kg weapon requires a bulky launcher and has a range of only two-and-half miles.
The much lighter Switchblade has a range of six miles, however, it is ineffective against a tank or armoured vehicles.
Military intelligence believes the weapon system will become critical to the next phase of the war.
It could erode the low morale among Russian troops because soldiers are left feeling exposed to sudden attacks.
In the early stages of the war, Ukraine had about 30 Turkish-made Bayraktar TB2 drones which targeted Russian tanks and devastated vital Russian supply lines.
Ukraine has used Polish-made Warmate drones, which weighs 5.3kg and can fly three miles and again dives at targets before exploding.
Ukraine is also using jamming signals to bring down Russian drones.
The fake signals disorientate the enemy drones.
