I can't see how this will give you a useful answer. Your poll seems to be asking a question to which there is an absolute answer (which some drone in main building could probably tell you) rather than a generalised one which is shaped by individual opinion. If, for argument's sake, there is only one unit in the whole Field Army with a TA CO and five people from his unit respond, your poll wil show five units with TA COs.
How do you propose to draw any meaningful conclusion?
We currently have a reg CO (it alternates) and I have to say that I think, with the TA being the creature that it is today, it should always be a regular position. Running a TA Regiment/Bn is a full time job that I simply don't believe TA senior officers have time to do. Reg officers also tend to have much better contacts allowing us to go to better places and get hold of better kit (temporarily!).
Or alternatively, they have little/no idea about what makes the TA tick, how to go about recruiting and retaining TA soldiers and officers and are surrounded by a regular Adjt, regular QM, regular RSM and regular TM.
He was our Sqn OC (V) when I transferred in, then went off to brigade as TA at the end of his time. Got the TM job a bit later under an S type (or whatever the correct terminology is these days) and took over as acting CO when the previous post holder (who was definately TA, he worked for the same company as I do) was killed in an RTA. Came back as CO proper once he got the rank.
