Gonzalo de Córdoba had raised the infantry soldier armed with a handgun to the status of the most important fighting man on the battlefield—a status he was to retain for over 400 years.
—Field Marshal Bernard Montgomery, 1983

That's not hyperbole from a historian trying to fill a word count. That's Montgomery — a man who fought in two world wars and commanded armor across North Africa — crediting a 16th-century Spanish commander with establishing the template that was still being used when his own tanks rolled through France. Think about that the next time someone tells you firearms are a "recent" development in how humans settle disputes.

The ditch wasn't just an obstacle—it was a force multiplier. It stopped cavalry momentum, funneled attackers into kill zones, and gave arquebusiers the time they needed to reload in the face of charging men.

This is the part that should mean something to anyone who's ever thought seriously about a defensive shooting situation. The weapon alone didn't win Cerignola — the 40-second reload time on a matchlock arquebus would've gotten those Spanish soldiers killed in the open. What won it was understanding the limitation and engineering around it. A ditch bought reload time. Today you're buying it with cover, positioning, and knowing your gear cold before you need it.

Cerignola handed the Swiss their first battle loss in 200 years.

Two centuries of battlefield dominance, ended because someone figured out how to put flanking fire on a pike formation. The Swiss didn't get slower or less disciplined overnight — the same tactics that had worked forever just ran into a new problem they had no doctrine for. That's a useful reminder that training for the threat you've always faced isn't the same as training for the threat you're about to face.

What's the most significant tactical adjustment you've made to your range training — or your carry setup — after realizing a previous assumption wasn't holding up?
