Going into Uniform; questions

If there are CIs there - no issues

No, but I can’t see why in extremis.
There were other staff attending, just no one else in uniform. Remember : family first, then work, then everything else in that order.

As above saying you need to have someone in uniform there as a pre-requisite is a nonsense. This is supposed to be a hobby.

As angus says a cdt SNCO should be able to take a squadron on a parade. As a CWO I was parade marshal for our BoB parade twice, the SWO was the RAFA branch standard bearer and the Branch approached me directly. I’ve been parade marshal for RBL and RAFA parades over the years.
