Amidst the shifting security landscape in Europe due to the war in Ukraine, Sweden and Finland have made decisive moves to align with NATO. Finland, with its strong military prowess, has officially become NATO’s 31st member, effectively doubling NATO’s border with Russia. Special attention is paid to Finland’s Utti Jaeger Regiment, renowned for its winter warfare expertise, a skill even the US special-operations community seeks to learn from.
