A video showing Ukrainian tanks on the move has been shared online following the news the UK will send a further 10,000 artillery rounds to Kyiv.
The footage, shared by Ukraine's Ministry of Defence, shows a column of tanks, with one flying a Ukrainian flag, driving through a field dotted with snow.
It comes after Defence Secretary Ben Wallace announced the UK would send the artillery rounds having delivered the first round of Sea King helicopters and committing to providing Ukraine with 1,000 surface-to-air missiles and 125 anti-aircraft guns.
Earlier this month, the Ministry of Defence (MOD) said Russian forces were now preparing defensive locations and building trenches 60km behind their current frontlines.
The MOD said Russia was prioritising "refitting, reorganisation and the preparation of defences across most sectors in Ukraine" in preparation for further assaults.
"Units have constructed new trench systems near the border of Crimea, as well as near the Siversky-Donets River between Donetsk and Luhansk Oblasts," the MOD said.
