She askes a lot of pertinent questions in that letter and I don't think she will like some of the answers, especially when it comes to the closure of 2 bases (even if one is not 24 hours) being all about saving money.
As for military involvement - it was specified (albeit vaguely) in the last process and should be in this one, but because SAR has slipped off MoD's to do list and the contractors (so far) won't make any commitment to directly transferring mil crews to civ and DfT just want the contract signed it won't happen.
