Excerpts from an article which appeared in the Australian Infantry Magazine in 2012. I'm curious if any major changes have been made since the article first appeared.
The number four will be a dominant theme in the new battalion with each team made up of four people and each command level - battalion, company, platoon – having four sub-units. The principle of four has been identified as a consistent theme in infantry. Having four elements enables a unit to simultaneously fix, assault, echelon and provide a reserve. In non-linear operations four also enables all directions to be covered. Having four sub-units provides a commander more flexibility in manoeuvring.
The new addition to the platoon will be three Manoeuvre Support Teams normally organised as a single section in the barracks. Each MS Team will have a team leader, support weapon operator, grenadier and sharpshooter and will be able to carry out all the tasks of an Infantry Team. However the MS Team will have more powerful weapons and will generally operate in the fire suppression role. The support weapon operator in each team will be armed with a 7.62mm MAG-58 general-purpose machinegun and the sharpshooter with a semi-automatic 7.62mm sniper rifle. As part of the ‘arms room’ approach the three MS teams will also have two additional heavy weapons to draw upon if needed. These will be one 12.7mm heavy machinegun and one 40mm automatic grenade launcher and their required tripods. To provide mobility to the MS Teams with their heavy weapons and ammunition each team in a light infantry battalion will also receive a small, lightweight vehicle like the para-deployable Supacat All Terrain Mobile Platform.
The flexibility of the new structure will be best seen in the way the MS Teams are deployed, either as their own section per platoon or by adding one team to each infantry section or even grouping all the MS Teams at company level as a very powerful MS Platoon under command of the Company Weapons Sergeant. The MS Teams will use the appropriate weapon for each particular situation and mission and provide a major boost to the platoon’s combat power. The final team in each platoon will be a four-person command team with the platoon leader, sergeant, signaller and medic.
