What guns - and what training - do the Vatican Swiss Guard have?

[TearsOfRage]

Despite their flamboyant uniforms, the Swiss guard of the Vatican are supposed to be pretty well trained soldiers. I've read that they use some sort of Sigs, and H&K's, but I don't know which ones. I would assume they've got guys on the rooftops with sniper rifles as well.

Does anyone have any more details?
