To get this back on track for artillery, no artillery unit would be full regular force.
In this lay-down, 1 Div is the defence of the homeland division. 2 Inf Bde is the regular force quick reaction airborne brigade, while 39 and 36 Inf Bdes are anti-access/area denial brigades. Every fires brigade has a Pan domain Regiment which provide an amalgamation of artillery command and control, military intelligence, influence activity, cyber and space warfare, and electronic warfare. Its purpose is to access intelligence and information across all domains and respond with appropriate cross-domain lethal or non lethal effects. It has a headquarters and signals battery with an STA/military intelligence coordination/targeting centre which links with the division’s and above sensor and lethal and non lethal effector resources; a medium range radar (MRR) battery; two electronic warfare squadrons; a cyber and space warfare squadron; and a UAV and long range loitering munitions launch battery.
1 RCHA has one regular force (airborne capable) high readiness field battery and two army reserve tiered-readiness batteries. Each battery is equipped with 6 X 155mm M777 howitzers (18 total) and 2 X HIMARS precision rocket launchers (6 total) on an arms locker basis. The regular force battery is the primary battery to support 1 IB (Abn) on Arctic operations and will be capable of fielding all six of the regiment’s HIMARS launchers if required.
Each coastal A2/AD brigade is assigned a HIMARS battery and a air defence regiment.
