5 RA is part of the Brit's 3 Division's 1st Recce Deep Strike Brigade Combat Team. 1st Bde is an interesting mix of the divisions primary recce elements (two armoured and two light cavalry regiments) and all its artillery (1 RHA [AS 90]; 19 RA [Archer]; 3 RHA [MLRS]; 26 RA [MLRS]; 101 RA [ResF L118]; 104 RA [Resf MLRS]; and 5 RA [STA]). The theory is of a force which can rapidly deploy forward and degrade an enemy advance while the two manoeuvre BCTs (12 and 20 ABCT) deploy. For a while I was contemplating that for my above napkin force and having the div cav regt (FGH) be part of 38 CAB. 5 RA's STA resources are not extensive and I don't think that their radars are as good as our MRRs and their acoustic system is the same (I think). Their deep FOO capabilities are in
4/73 (Sphinx) Special OP Battery. As
@KevinB points out, that type of observation is also part of various special forces special reconnaissance operations.
Interesting. When I served there in the 70s, there was an active rail line that paralleled Hwy 17 all the way to Ottawa. I just looked at Google Earth and it now seems to stop at Mattawa with the last major yard being at North Bay.
I've done some rail moves of M109 regiments both in Germany and also at Shilo for RV81. It was an eyeopener as to how well equipped the regiment in Germany and the DB was for rail moves while both the army in Canada and CNR/CPR are very poorly equipped. What was a one day job to load a regiment in Germany took four days in Canada - the cars sucked and the dunnage was slipshod. This is the railhead in Shilo. A bit short and one needed to load in segments but it was workable. Rail moves are something that need to be exercised regularly if they are to be efficient.
