Ten Rounds Rapid (or Space Invaders on the Marne?)

This was a quick play test of a game Martin has been working on recently. In it, the player(s) runs a British battalion being attacked by the field grey hordes (an entire regiment of them) in August 1914. The Brits start deployed as per their pre-war doctrine with a firing line, support line and reserves. The players job is to blunt the German attack by managing his resources - manpower and ammunition. To add to the fun, once deployed on table, troops may not move to the side, but only forward (or back).
The game went well, lasting for about 45 minutes and a subsequent discussion produced a couple of ideas which might streamline it a bit.
All the toys were from Martin's 15mm collection. He ran the game while I commanded the Brits.
