As a guess I'd put it down to phys, probably its also a combination of white fleet comms exercises and tactical non comms exercises (i.e. soldiers have no experience of defending a comms site esp 2 (NC) Sig Bde soldiers).
choosing signals units
Realising I had similar thoughts and acted on them a few years ago, moving from a REMF unit to a 'teeth' arm signals unit (ok we work with infantry but from nice offices in regional Bde HQ). Its a lot better, work with modern comms systems, have customers giving us problems but ... I actually enjoyed being under canvas, getting cold and wet. Awaking in the middle of the night and getting my switch bitches to launch a counter attack .. it was fun but I like the geeky side aswell.
Where is the one Army concept when u need it, why can't I do both like a regular? Yes guicci units exist but their all down South (ok I know thats not entirely true.. I have had a couple of PMs trying to subvert me )
I do miss the days pre SDR where I put the 352 on me back and lived under a poncho/canvas
