At the armoured regiments, assault gun companies (Infanterikanonvagn 72, 73, 102 and 103) were also trained, self-propelled anti-tank companies (Pansarvärnskanonvagn m/43), anti-aircraft gun platoons (40 mm L/60) and crews for self-propelled assault guns (Stormartillerivagn m/43). In 1957, the Norrbotten Armoured Battalion (P 5) was raised to meet the needs of armoured combat units in Upper Norrland. In the same year, P 3 was reorganized into I 10 and became an armoured infantry regiment. I 1 returned to the infantry.
