I think 56 Fd has been punching above its weight ever since
@Petard was there as an RSSO a decade or so ago. Which is interesting as its a dispersed regiment with armouries in each of Brantford, St Catherines and Simcoe.
Back in around 2009 and 10, the plan was made in support of Force 2013 giving ARes units specific mission tasks (in spite of but working within LFRR) In short, the 18 regts and independent batteries were tasked to form a total of 12 dismounted FOO parties, 25 gun dets, 12 gun troop CPs, 3 HALO tps and 3 LCMR tps for a total of 533 all ranks. The expectation was that this would allow the sustainable operational deployment of 2 FOO parties, a two-gun troop and 1/2 each HALO and LCMR troops per LoO 3 roto (for a total of 58 all ranks per roto.) A further 617 all ranks were assigned to domestic ops duties. At the time 56 Fd was only tasked with 1 x M777 gun det and 1 HALO tp.
Problematic was the equipment side of the equation as the STA gear could not be decentralized sufficiently, the availability of training opportunities on the M777 were inconsistent across the RegF regiments and the ARes gunner equipment was slowly self divesting itself. 2 RCHA has had a good record of supporting ARes training and involvement.
