What challenges would the UK face in contributing troops to a peacekeeping mission in Ukraine?

The UK would face significant personnel and equipment limitations in contributing to a Ukraine peacekeeping mission. With only 75,000 full-time army personnel plus 24,000 reserves (many in non-combat roles), and troops already engaged in 60 operations across 44 countries, Britain lacks the capacity for a substantial deployment. A military expert explicitly states: "We haven't got the numbers and we haven't got the equipment to put a large force onto the ground for an extended period of time." Unlike previous peacekeeping missions in Bosnia or Sierra Leone, a Ukraine deployment would be much larger, lack UN/NATO protection, and face strong Russian opposition.
