What are the current challenges facing the British Army regarding its military readiness?

The British Army faces significant readiness challenges as it has shrunk from over 100,000 strong during the Afghanistan deployment to just over 70,000 personnel currently. This reduction has strained military resources, with Afghanistan being the last major test for the force. Additionally, the army is struggling with recruitment and retention issues that affect its operational capabilities. European nations, including the UK, are now being urged to increase defense spending in response to the Ukraine conflict, which serves as a wake-up call regarding military preparedness. The situation highlights how support for Ukraine comes with financial and strategic costs for Western allies.
