This is actually the scope of ambition being looked at. It's a genuine, "How would we fight for years?" Question.
And as we go through this there's a realization government wide (not just CAF) of how daunting the task is.
It's all the way from basics (getting the CAL DAL right) to how would we manage strategic comms to mobilize society in the age of AI fakes, to how do we manage the mismatch between weeks to mobilize PRes to months to mobilize Strat/Mob Res to years to mobilize industry. All of this kinda stuff is actually being staff checked with outputs on everything from legislative changes proposed to procurement to changing force design to changing mandates of agencies. CCG moving to DND, for example, is just the first step in looking at underwater infrastructure protection. There's discussions, for example, on what legislative changes might be needed to enable more reserve service as part of creating that mobilization reserve and growing PRes substantially.
But it's like eating an elephant. This is easily a decade long project.
