This happens to be 15mm standard for many rules which won't help if playing some using standard 25mm basing but that won't matter if both armies are mine. It does mean I can make impetus units out of 3 bases or if using 2 bases can match Ron's units for playing on a hex grid. I just tried it today using Comitatus and it worked great, well some units were on 40's from earlier experiments, others were singles on a 20mm frontage and I fudged the rest. Getting ready for the game got my enthusiasm levels up high enough to finish 4 more Persian Clibinari and rebase them with the existing ones to finish that unit.
I also got a start at refurbishing my old Valdurian Royal Horse Guards to serve as Guards for the Queen of Marakanda. I picked these Rohirrim lads up at the Minifig stand in the wargames tent at Aldershot the summer of 1974. My first metal cavalry. To keep up their status next to all those RAFM & Garrison horses I need to remount them, they've borrowed some PB horses here.
Anyone need 10 x S range 1/2 armoured horses?
First time in battle in decades and another victory to their credit.
