The linear formation was a common tactical arrangement on the 17th- and 18th-century battlefield. Infantry would form in lines across the field, in ranks two to three deep. Each rank would then fire one after another, advancing as they did (while stepping over fallen comrades in the front rank). The tactic, despite its popularity, had several flaws, not the least of which was it had to be conducted on wide and flat terrain where troops were exposed to enemy fire. And it worked best when the opponents fought the same way. (The British used this tactic in the War of Independence, only to be massacred by Americans who used far less rigid guerrilla tactics.) So what’s that have to do with social media? marketingmag.ca
