Shotone,
Not a criticism but picking up on your last point. I have yet to see a single member of the military or MoD CS held to account for any equipment deficiency or shoddy acquisition. Which can only mean that it did happen and I missed it, or it hasn't happened, or there have been no examples of shoddy acquisition. I think the last one might be unlikely because we wouldn't have needed Levene and Gray et al to sort out a problem if it wasn't there.
I can personally think of three senior figures at DE&S who are useless - but they get shuffled from team to team and their incompetence is an 'in joke' but they don't get sacked.
On a similar note, I have noticed that no-one has gone after Dannatt, Stirrup, Torpy, Band et al for their pensions (or even just an apology or public admonishment) - surely that's where we should have started when it became apparent that their generation created the £38 bn hole that we have laboured long and hard to fill?
