Their advert in Battlegames, issue 5, lists the new packs as:-
SB41 ~ Dismounted Camel Corps/Mounted Infantry Command
SB42 ~ ditto Firin Line
SB$£ ~ ditto Skirmishing
SB44 ~ ditto Kneeling camels and one Camel Corps sentry.
So, that means 3 seperate camel packs, plus three command figures you may not use, plus three spare rankers in the firing line to make a 12 man unit. Not the most helpful move from the Perrys imho.
