Don't matter where you are armed services/general public service/politics the bean counters justify their position by screwing with what works to save a couple of peanuts on follies that defy logic.
I.E as Geeram alluded to why have something that works excels in what it does and will be around for a long time yet, nope lets get something that can do 1 job well like lift heavy things and we will overlook the short comings because its new and sparkling.
Been in companies where the bean counters come in and absolutely go to town like a wrecking ball, whilst at times finding out in the long run the learned system through trial and error was in some cases better than the few pennies they saved.

Anyway as long as they feel justified they consider themselves wanted just like an ash tray on a motor bike!!!!!!
