I had gone back to lurking for a while but I can't help but get in on the changes to Army.
A few points I might throw in:
1) 3BDE is noted as retaining its amphibious capability, as distinct from littoral. The role of 2RAR in supporting the ARE/ARU may not change as a result, assuming the LHD at least remain in service. 2RAR could move to support the littoral lift groups (LLGs, forgive the acronyms) via detachments, or the groups themselves could field their own pre-landing elements. Either way, if they are intended to operate independently and dispersed they are going to need a way to operate safely across the Coral Triangle.
2) The LMV-H are noted as existing in each of the combat brigades from 2024. While this may be purely speculation, as the infographic may just be indicating planning, it could indicate a faster timelime for LMV-H over something else, or some interim decision for training such as leased craft, if they are available (like 1BDE is doing at the moment, ref. 1:33 mark).
3) There is no mention of AS4 post-2024. Currently there are three battalions of AS4, with one (3RAR) to transition to AS21 and another disappearing from ORBAT (7RAR). How 6RAR transitions will be interesting, presuming there is no surplus of Bushmasters available. Further, only 9BDE is noted as fielding G-Wagon post-2024 - though this may be looking too far into it.
4) This still appears to be a planned expansion of the Army, regardless of 7RAR being slashed. Water transport will need to grow tremendously (regardless of mixed crewing with RAN), RAA is expanding and will need to retain old training pipelines also, and 5/7RAR and 2RAR may need to grow on an individual basis in order to enable littoral lift groups. Close combat, as per DSR, is on the backburner - though I would stress my desire to not retain old or inadequate systems.
5) A lot of work to concentrate effort it would seem (minus littoral lift). All tanks moving to Townsville, 10BDE being fires, while 16BDE helicopter fleets are being concentrated so contractors can better support. Brigades are returning to being specialised and, as per COA in previous address, are largely returning to the command of 1DIV.
Hopefully this one sticks and there isn't another chop and change. While I can see the appeal of having Army closer to population centres, especially when recruiting is hard, I can also see the advantages of being aclimated to the tropics and being positioned towards our interests. At least a lot of estate has already been set up in these areas, though not all of it.
Hopefully we can keep up a good tempo, considering current issues around recruiting/retention, restructuring, and possibly impending DACC tasks. Probably gonna return to lurking, but had to jump in with my 2cents considering it is probably the biggest news thats gonna happen to the green for a while.
