 CONT: When Captain Miller and his men decide to stay at the bridge  after finding Private Ryan, all of the equipment is inventoried, and  Miller is told that they have two .30 caliber machine guns. One of  them is seen being hauled up into the bell tower, and later, Mellish  tells Captain Henderson he will go and get him some ammo for the .30  caliber that Henderson has. As Mellish walks away from Hendersons  machine gun, another soldier walks by carrying another one, even  though that one is supposed to be in the bell tower already. For  this scenario to work, there would have had to have been three  machine guns.
