We all know we haven't got enough AT, and that the AT we do have doesn't all have all the kit.
So if there is too much tasking for the available assets it's a question of priority as to which tasks are completed.
Which is more important - op flying in active theatres resupplying the boys and girls, or qualifying a bloke in a discipline he'll never use in anger so he doesn't get bantered in the barrack block?
No question that ideally we'd do it all. Not with this level of tasking though.
