I wouldn't read too much into that diagram. I think your post of July (#9331) is more instructive, specifically the slides shown by Brigadier Ian Langford Director-General of Future Land Warfare.
In the second one, you see that 1 Brigade has no artillery allocated to it; 3 and 7 brigades each would have 2 SPHs and 4 M777s; and 9 Brigade would have 8 SPHs. In addition, there would be 42 SPHs and 32 M777s shared between two staging locations, and 6 and 14 allocated to training respectively.
What can we extrapolate from that? I think you could see the artillery regiments of 3 and 7 brigades each having two batteries with the M777 and one with the K9, while 9 Brigade would have three batteries with the K9.
Incidentally, we had 54 M777s, but have given 6 to Ukraine, which leaves 48. Four batteries with six guns would require 24 - half. Similarly, five batteries with six guns each with the K9 would equal 30, or half the 60 we intend to buy.
I do find the intended structure interesting but I'm mindful that it's always evolving.
For many of the units their intended role is based upon equipment not currently in service.
This is not a criticism, just the fact that it takes many years to role out new vehicles,watercraft and aircraft.
What we aspire to in 2022 many look very different when the actual fleets of stock are acquired in some cases up to ten years time.
Basic overview is we are now evolving a four Brigade structure with one lighter motorized Brigade based in the north developing a coastal maneuver skill set.
Of the other three Brigades, two appear to have a similar structure, while the SA based 9th Brigade looks to have a heavier armoured structure.
Not sure if this is a long term thing or just to trial out new kit and concepts pending introduction of the outcome to the other two brigades ( 3rd and 7th )
Again Army appears to always be evolving.
Good to see 13th Brigade out west getting some focus and additional regular support.
Somewhat puzzled as to why Perth with half the population of Melbourne can field twice as many battalions!!!!
Not that I see Melbourne as under threat, but as a contribution to the national effort a city of five million should be better utilized.
Melbourne did have two battalions back in the late 70's.
4th Brigade does get 12/40 Regiment from Tasmania which makes sense.
Would be interested as to whats happening with the special forces.
Will the Commandos get an additional Sqn / Coy?
An interesting decade ahead.
