Back during the 250th of the F&I, 2008 at the battle of Carillon (Ticonderoga), the French were firing from behind the reconstructed log fortifications. Those in charge wanted us to pass our muskets to the man in front like they did in this video. We said, "No way will we pass a $2000 gun up to someone we don't know, and have no idea how he will care for it." So instead of passing the guns, we took turns moving up to fire. I really think it works better that way. It sure worked for the musket formations in the Thirty Years War a hundred years or so earlier.
