I agree with this article. I have noticed a few military or former military personel play. Isnt Alan former UK military?
Yes I am, and I remember playing wargames while serving, both 15mm ancients, and with toy tanks as we figured out ways to better move as a unit through terrain.
Another example, maybe a less polular one, but it should illustrate the point; In WWII the SS used to teach their troops "Game theory" X number of troops with rifles at x range can hit x number of enemy in open, treeline.. etc. Its a great way to teach troops how likely it is they can get something done with the tools in hand.
cheers,
Alan
