Both Norway and Denmark were quick to join NATO after its establishment in 1949. However Sweden and Finland remain neutral, each for their own reasons, but always wary of their massive Soviet neighbour.The Finnish armoured forces field T-72fm1 , T-72fm2 and T-55m Soviet tanks with local improvements and newer western technology applied. Their Jaakari infantry are mounted in BMPs and BTR-60s with missiles , recoiless rifles, and mortars for fire support. The Swedes are mostly self-sufficient with their own turretless S-Tank with its autoloader and powerful gun. Their well armed infantry are mounted in the Pbv 302 APC armed with a 20mm autocannon. Supplementing their locally manfacured equipment the Swedes also field the Centurion tanks, with upgraded fire control systems and Explosive Reactive Armour. The norwegians and Danes have more conventional equipment, both fielding Leopard 1 tanks in their armoured forces and M113s for their mechanised infantry. The Danes also field two Variants of Centurion tanks.
