My first two packs of Airfix soldiers were the old style German Infantry and 8th Army.
The first 'toy soldier' games that I played involved these. I remember my friend Iain and I would set up the opposing sides in his lobby using wooden farm buildings built by his grandad. We would then set about each others forces by rolling marbles or firing matches from Iain's Dinky field gun.
I still have fond memories of those games. They really locked me in to a lifelong passion for gaming with toy soldiers.
