Of course there's disquiet. As you should see from endless threads on the 'Sigs' board, they never stop winging. If it's not about their kit, their exercises then it's individuals in charge. In fact it seems that if there's nothing to complain about, they'll make something up.
Makes the soldiers in the Corps look like krap and if you can't have a moan with a little humour and a lot less bile, you should all just pack it in.
