My son did work experience at Thales Bendigo a couple of weeks ago and one of his jobs was loading the magazine of a naval gun that was under test... it apparently was very hard work keeping up with the rapid fire gun.... it fired in 5 round bursts. The older workers let him do the actual loading as he was a bit more nimble than they were.
He also help build some Bushmasters and went for a drive in another Bushmaster.
