Great Lakes Attack Squadron is the Michigan chapter of Model Warship Combat Inc. The MWC is dedicated to the building and battling of radio-controlled 1/144th scale warships from World War 1 and 2. Using CO2 powered BB cannons, ships ranging from PT boats to battleships shoot holes in each other's hulls, eventually sinking (if the pump cant keep up...). The damage is easily repaired within minutes to return the ship to battle.
