BigAvo,
Sounds to me like you went for selection a few years back (3 or 4) and didn't pass.
Your info is at times out of date and at other times completely wrong. Baz does know what he's talking about. Recruits get to see very little of what the regt does until very late in their training and operations aren't talked about too much, same with eqt.
Other Guys,
If you want to go for selection, then as someone else said contact them directly, contacts can easily be found on the internet on the proper site and not forums like this, where disinformation is rife on topics such as this.
As for feet hardening, do the tabbing and let mother nature do the rest, the only thing you should put on your feet (apart from boots and socks) is white zinc-oxide tape in my opinion although I've never tried second-skin or other products that are similar.
Cheers,
Greenboy (aka Walter?)
