[@In Crypt Dead] All zats and Staff weapons are things salvaged from the enemy. They are a non standard equipment and aside Teal'c who's a Jaffa, no one else from SGC would be using a staff weapon unless nothing else was avaible. So yeah staff weapons are unlikely to be brought just like that. For zats it's more possible, but at this point in time it's still a non standard issue thing. It's going to become aviable eventually and you can always salvage one from the enemy during the RP if you so decide.
