The UK has agreed to provide additional equipment worth nearly £1m to the Ukraine Armed Forces (UAF) to support the soldiers through winter.
The equipment includes 170 large tents, 170 heating units, and 600 sets of cold weather clothing.
Fallon said: "The UK is committed to supporting Ukraine's sovereignty, independence and territorial integrity.
"That is why we are providing this gift of non-lethal equipment, to further help prevent Ukrainian fatalities and casualties, strengthen their defensive capability and build their resilience."
UAF personnel still remain in the areas affected by conflict, despite the latest ceasefire.
The UK is providing the equipment to prevent further fatalities and improve resilience on the ground.
Earlier in 2015, the UK decided to send 25 more training personnel to Ukraine, increasing the number deployed to 100. The new training personnel will begin heading to Ukraine in April 2016.
The UK has already started a training programme in Ukraine to increase the infantry, medical and survival skills of the Ukrainian soldiers.
From next week onwards, around 25 UK teams will provide training to the Ukrainian Armed Forces in nine locations.
The teams will provide further training to the Ukrainian soldiers to develop their skills in logistics, urban defensive operations, and media and operational planning.
