Ukrainian troops are thought to have used British Challenger 2 tanks in their offensive inside Russia, Sky News understands.
If confirmed, it would be the first time British tanks – operated by Ukrainian soldiers – have been used in combat on Russian territory.
The Ministry of Defence in London declined to comment on operational detail. Ukraine’s armed forces did not offer a comment.
However, the UK has confirmed Ukraine is free to use British weapons on Russian territory, according to government policy.
A source said this included Challenger 2 tanks and signalled that they had been used during the Ukrainian incursion, which began on 6 August.
Details on how and when Ukrainian forces deployed Challenger 2 tanks within the Russian region of Kursk were not immediately clear. Neither was the number of tanks that may have been involved.
But Ukraine’s powerful 82nd Air Assault Brigade is the unit of the Ukrainian armed forces that has been operating the British main battle tanks since last year.
Elements of the brigade are confirmed to be taking part in the Kursk offensive.
The UK agreed to give Ukraine 14 of its Challenger 2 tanks in January 2023 in a move that prompted Germany and the US to follow suit with their versions.

One of the British tanks was destroyed in operations inside Ukraine last September – the first time the Challenger 2 had been taken out in active combat.
In service since 1994, the Challenger 2 tank weighs 62.5 tonnes and is armed with a 120mm rifled gun and a 7.62mm chain gun.

Under UK government policy, the use of any weapons given to Ukraine by the UK must be in line with international law. The military assistance is aimed at helping the Ukrainian military defend itself from Russian attack.
The Times reported on Wednesday Sir Ben Wallace, the former defence secretary, had disclosed how during his tenure he gave permission for Ukraine to hit targets inside Russia using “whatever weapons [were] supplied to it”, with the exception of long-range Storm Shadow cruise missiles.
He suggested the same rules applied to Ukraine’s Kursk operation in Russia.
Sir Ben was quoted as saying if the attack was designed to go after logistics and infrastructure supporting Russia’s invasion of Ukraine, it was “perfectly legitimate” for Ukraine to use British weapons.
