"An ounce of sweat saves a gallon of plastic."
~Sarge, Army Men II
No clue what size they are, I remember a disastrous incident though, I set up the Tan and Green men to fight each other, I decided that I would use Bottle Rockets as artillery, I was shooting one of on the tan side against the green side, and well, it hit a rock, did a 180, and took out a Tan tank and 17 tan soldiers, one of the worst friendly fire incidents in the history of Army Men warfare. After that I just chucked M-80's at the Army Men. Word of advice, don't use bottle rockets, stick with M-80's, and it can be fund to bury a 100 roll of thunder bombs under the army men and set it off, like a massive artillery barage or something, make sure you bury it about 1" under the sand, any deeper and it wont have any effect, to shallow and they start flying all over the places.
