We used British 1918 lists with a few mods. No grenades for normal troops, only bombers (one platoon per company). There were a few new rules that we were using that will be in the next supplement but I'm not at liberty to give that info out atm.
It was a very good game considering it was our first using the armies at Gallipoli. I need to get painting up my second company so we can play test some of the other scenarios.
For those that are interested all the figures are Gripping Beast and the trenches, craters and trees are from Ironclad Miniatures.
