What challenges would the UK face in contributing troops to a Ukraine peace deal?

The UK would face significant numerical and logistical challenges in contributing to a Ukraine peace mission. With only 75,000 full-time army personnel and 24,000 reserves (many in non-combat roles), British forces are already stretched thin supporting 60 operations across 44 countries worldwide. A Ukraine deployment would require substantial forces, with NATO estimating between 50,000-100,000 troops needed overall. Such a commitment would likely dwarf the UK's current military engagements and may not be realistic given existing obligations, despite the UK's apparent willingness to participate while other European nations like Poland and Germany express reluctance.
