Don't forget to add to your wargame for added realism that on a weekend we went home or the singleys moved into the pub. You might as well leave a sign on the beaches asking the Russians to come back monday morning, as it's just not cricket to work weekends.
When I was at Coningsby while we had the Tornado Air Display Variant the most heavily defended part of the UK on a friday evening was the Sports and Social club, above the JRM. Then the Ruskies would have never captured the Black Swan or Ratties on a Saturday night.
The biggest disaster in your war-game could be if you roll two 6's which means that Pizza shop on the walk home from the pub has closed and you wake up next to a local one eye potato picker with webbed feet.
