I pitched an idea to my leadership, at an innovation fair, that I could develop rules, scenarios, and a kit to conduct training using tabletop wargaming. They loved the idea an approved funding for 1 'proof of concept' kit to show that it works. So I have been working on the rules (which will be a heavily modified version of Danger Close from Empress Miniatures) and the initial scenario while I paint up all the buildings, terrain, and miniatures. I chose to go with 20mm as I felt it gave a better ground scale feel if playing on a smaller table.
