Deep fires and the British strategic posture: does the war in Ukraine validate it?

The Russia-Ukraine war presented an unintended chance to assess the British strategic posture regarding deep fires. The deployment of guided rocket artillery systems by Ukrainian forces in 2022 altered the land battle dynamics significantly, especially with the modern Western deep fires by the US, UK, and France. This study analyses the evolution of the UK defence policy and land force structure and the impact of deep fires in the first phase of the war, and discusses challenges ahead of Britain due to the ongoing conflict. This perspective might apply to other cases, including Brazil, as we drew upon critiques mainly directed to the over-reliance on technology over combat mass due to the re-emergence of conventional warfare.
