HCDC is a very positive voice on behalf of the men and women in dark/light blue and green.
However, it is largely ignored by HMG. For example, HCDC have pressed for an independent complaints commission for the Armed Forces and have been ignored. HCDC were also very critical over the pension changes and the lamentable lack of consultation. I believe that Committee member (and much-missed) Rachel Squire MP used the term "stabbed in the back" with reference to a certain (unlamented) former Secretary of State.
There is little effective Parliamentary scrutiny over the Armed Forces and the forthcoming Bill seeks to lessen the limited oversight (offered by the annually-renewed Service Discipline Acts) even further.
