Exact same thing as AlphaPlayers, BravoPlayers, CharliePlayers, and DeltaPlayers, except this is for spectating players. I know you could just do SpectatingPlayers := NumPlayers - AlphaPlayers - BravoPlayers - CharliePlayers - DeltaPlayers but that is... using a global byte would make it a bit cleaner for when the number of spectating players is needed.
