All members of Gold Team have effective military ranks. For the purposes of this game, most characters are assumed to hold the rank of Corporal. However, it is permitted for characters to hold higher ranks - but an additional entry fee is charged (ie. as well as the team fee). This also goes to charity of course, so it's really just an excuse for generous players to donate a bit extra !
Note: The Heads of Division are equivalent in rank to, for example, the General of the U.S. army. As such there really shouldn't be more than one per team ( in the unlikely event anyone feels that rich ) !
