The convoy to Kiev early on in the war was attacked with Western weapons like the British made NLAW anti-weapon. It made a huge difference in deterring the Russians from further aggression west of the Donbas.
Those anti-tank weapon are the NLAWs, or next generation light anti-tank weapons, which have been so effective against Russian vehicles that have been left exposed as a result of a lack of military coordination. Britain’s involvement in training troops dates back to Russia’s annexation of Crimea in 2014. In the face of some opposition within Whitehall, British military help for Ukraine was conducted through Operation Orbital from 2015.
Ukraine’s former president Petro Poroshenko has said that he inherited a decrepit armed forces when he came to power in 2014, which was transformed by western aid. About 22,000 Ukrainian troops have been trained through the programme.
Meanwhile, the NLAWs have been very effective, with some sources reporting an extraordinary 90% hit rate. The weapons, which can be swiftly deployed at close quarters and discarded, are lighter than the similar Javelin anti-tank missile systems, which the US has been dispatching to Ukraine. So far, Britain has sent more than 4,200 NLAWs.
