Some sort of Combats, most place sell repro CADPAT, good boots, good goggles should do you fine, unless you're going for a certain theme or look, then get what suits... a Helmet is nice, but not necessary, a boonie would do fine...

Edit: Snow_Raven beat me... damn fast typer/short poster... Yeah, that would make a difference too, sorry, I went on the assumption of playing out doors, woodlands... just because that's what's typical around here... but if it's CQB you'd be looking at something different....
