Boscombe Down isn't only about the TPs. There is a whole load of other clever stuff there including, to name but few, environmental chambers, EMC testing facilities, Night Vision Systems Test House, and other specialist testing facilities. Are you suggesting that you move one of each of these to the various locations where the OEUs reside or shall we move the OEUs to where the specialists are.
Boscombe could and should be a one stop shop for everything that requires to be tested for the military, and that should include the Operational expertise available on the OEUs, although to be fair, all the tps that I work with have recently come from a front-line background, it's practically compulsory to even make it to interview.
Those of you who slag the place off as slow and irrelevant should come along and see for yourself what actually gets done to ensure the stuff that gets to the frontline does what it says on the tin.
