 In the inter-war years, the machine gun battalion concept was discontinued in the Australian Army, and in the 1920s medium machine gun platoons were added to the organisation of standard infantry battalions.According to Alexander Rodger, as a result of the decision not to re-raise machine gun battalions in the early interwar years, no battle honours were subsequently awarded to the 5th Machine Gun Battalion – or any other World War I machine gun battalion – as there was no equivalent unit to perpetuate the honours when they were promulgated by the Australian Army in 1927.Nevertheless, the machine gun battalion concept was revived again in 1937 as fears of war in Europe surfaced again, and four Australian Light Horse regiments – the 1st, 16th, 17th and 18th – were converted into machine gun regiments.
