Well with payments under the new Armed Forces Redundancy scheme being so small (28 years service and over 3 years left to serve equals 3 months pay maximum, which for me is around £10,000) I don't think many will get anywhere near £30,000. As you say the pension/redundancy schemes and HMRC have been manouvering to make it far cheaper to get rid of people.
Incidentally that £10,000 is approx £300 more than the statutory redundancy payment required by law, long gone are the 18 months of pay redundancy payments (caveat: the amounts I quote are for personnel who have passed their immediate pension point I.e. 22 years for ORs who were on afps 75).
