The regiment would have nothing larger than small-scale artillery pieces, generally known as 'mountain guns' - basically low-calibre artillery pieces that can be taken apart to transport - while on a more general, squad-to-squad level, mortars and heavy stubbers would indeed be probably the heaviest weapons yes.

In terms of vehicles, due to our regiments role, vehicles are pretty much a no-no; whether this is due to needed stealth in the field, deployment in an alpine environment, etc. We're a light infantry regiment, so any supplies and heavy equipment is going to be carried primarily by the soldiers themselves or, at a pinch, domesticated grox.

In terms of size, yes, the regiment is roughly three companies [[i]kompanies[/i]] or 3,000 or so men split into 1,000 in each company and then further into three platoons each - there is however no standardised size for a Guard regiment in 40k, so it could get bigger or (or most certainly) smaller over time.
