Another good post from Brushbeater. Read the whole thing.
Key thought: “But skill, specifically mastery of basic skills, can never be supplanted by a product. And in turn, no product will make you better if the fundamentals ain’t there first. Those fundamentals, with some very basic supporting gear, lay the foundation for you to be effective whether it’s combat weapon[s]craft, movements in potentially hostile environments, or tactical communications. The basics of anything never, ever change. And you might be surprised at what can be done with just a mastery of what’s simple.”
