Australia's 3rd Brigade armour expansion brings major logistics challenges
Australia's 3rd Brigade, based in Townsville, Queensland, is undergoing its biggest modernisation since World War Two, with its heavy armoured vehicle fleet growing by 630% in three years and personnel rising from 3,200 to around 4,000. Commander Brigadier Ben McLennan says logistics — particularly fuel and ammunition supply — is now the biggest challenge. The transformation aims to make the brigade potentially the most lethal armoured formation of its type on the planet.

TOWNSVILLE, Australia — Based in Townsville in northern Queensland, the Australian Army’s 3rd Brigade is undergoing a massive transformation, as the heavy armored formation absorbs whole new fleets of vehicles.
Yet this modernization push has major knock-on effects in terms of logistics support.
Brigadier Ben McLennan, the brigade’s commander, told Defense News, “The Australian Army is undergoing its most significant recapitalization, at least since World War Two, and I’d say it’s happening at record pace.”
Yet he noted most of his bandwidth is invested on how to sustain this armored brigade that has “the potential to be the most lethal formation of its type on the planet.”
McLennan quoted figures to underscore the criticality of logistics. “This brigade’s heavy armored vehicle fleet increases 630% in three years. Also, the brigade is going from 3,200 to around 4,000 personnel in three years,” including growth in “the very, very important logistics echelon.”
As another example of the growing sustainment burden, McLennan said his former multirole combat brigade is moving from an average of 40,000 liters (roughly 10,000 gallons) of diesel per day in high-intensity operations to a daily fuel requirement of over 300,000 liters (79,000 gallons).
Bulking up on armor
An important reason for such a thirst for fuel stems from heavier armored vehicles. For example, the 2nd Cavalry Regiment has already received its full complement of new M1A2 SEPv3 Abrams main battle tanks.
Furthermore, two armored engineering squadrons will have received all their Abrams-based combat engineering vehicles – the M1150 Assault Breacher Vehicle and M1074 Joint Assault Bridge – by the end of 2026.
The first Hanwha AS9 Huntsman self-propelled howitzer (SPH) has arrived in Townsville, and due next year are Hanwha AS21 Redback infantry fighting vehicles. Then, Rheinmetall’s Boxer 8x8 combat reconnaissance vehicle will start replacing the long-serving ASLAV in 2028.
McLennan added, “Our stock of M88A2 recovery vehicles has tripled over the two years that I’ve been here, and our armored logistics battalion increases by a subunit at the end of this year.”
It is not just heavy armor that is snowballing either, for the brigade is adopting greater numbers of aerial drones for logistics, surveillance and attack. The commander revealed that unmanned ground vehicles will arrive soon too, including variants that can enter minefields dragging a tube full of explosives to clear paths.
All these new weapon systems require rearming too. McLennan spoke of the need for resilient logistics units “to move the heavy natures of ammunition and the increasing types of ammunition: 30mm, Spike LR, different types of 155mm, a whole lot more 12.7mm.”
He pointed out the brigade’s heavy-duty expansion “will take us from about 30 pallets of ammunition a day to 105 when we factoring us conducting high-intensity combat as a brigade with all our equipment. So it’s a significant transformation.”
Artillery advances
The brigade’s 4th Regiment, Royal Australian Artillery is trading in its M777A2 towed howitzers for the AS9 Huntsman. The first 155mm SPH reached 106 Battery in late May, and the unit will eventually have a full allotment of six AS9s plus three AS10 armored ammunition resupply vehicles.
The regiment’s two other batteries will be identically equipped by the end of 2027. Significantly, the 4th Regiment is moving from four M777A2s per battery to six AS9s, with McLennan claiming the new structure and platforms “increase our capability, our firepower, our mobility, our protection by at least 300%.”
Maj. Fergus Robinson, commander of 106 Battery, highlighted: “One of the biggest challenges for soldiers will be vehicle husbandry – this is your vehicle, this is your home and you’re responsible for it. Their ability to maintain the vehicle, as well as the weapon system, is extremely important.”
Given the hulking size of the 48-ton AS9s and their supporting AS10s, the 4th Regiment will receive M88A2 Hercules recovery vehicles for the first time. “That will be something where we need to practice and develop our own skills to get it to a mature point, where we’re confident we can do this under night, under fire, under contact,” Maj. Robinson admitted.
Base infrastructure
All this expansion in capability requires new infrastructure, with McLennan discussing a transformation at the brigade’s home turf of Lavarack Barracks in Townsville.
“We’ll have opened by the end of the year probably the best common user facility, certainly in the Southern Hemisphere and perhaps the most modern in the world, that services all these fleets with light- and medium-grade repair.” That infrastructure work continues over the next couple of years as new equipment pours in.
As an example, the artillery regiment opened a new maintenance hangar in May. This features a 10-tonne gantry crane that permits vehicle power pack changes.
McLennan added: “Concurrently, additional range facilities are being built up at the Townsville Field Training Area to enable the armored brigade to achieve its mission-essential task lists in training year on, year on.”
Greater lethality
While some army units around the world are seeking to become lighter and more mobile, the opposite is true of Australia’s 3rd Brigade.
As McLennan explained to Defense News: “The fact is that the combined-arms fighting system – not just tanks, but armored engineering vehicles, self-propelled artillery – are just as relevant, if not more relevant, than ever. They’re adapting to the threat and also the technologies that can help them reach a level of potential that we previously couldn’t.”
He said “we’re very, very focused” on this transformation, and “we’re drawing lessons from others who are doing it for real routinely.”
As well as transforming the 3rd Brigade, the Australian Army is simultaneously raising a Littoral Maneuver Group, maturing its 10th Brigade equipped with HIMARS and NASAM, and inducting the AH-64E Apache helicopter.
Is Australia investing enough in its land forces modernisation?
