Your friend hasn't seen the tiger close enough to notice what it's made of. You should, when relevant, draw attention to it with historical and contemporary examples.

In fact, military logistical analysis is a pretty good way to introduce people to thinking materially. The line many people use is "I'm sure your AR15 will do a lot of good against a tank." But let's game that out. What does a tank need to exist in the field? It needs fuel, it needs to be mobile, the crew need to eat and sleep, they need to get out sometimes to piss or at least to empty the piss bottles, they need communications, they need infantry protection because otherwise the Abrams is so loud you could literally sneak up on it with a parade, and all of a sudden you're mapping out a web of logistical choke points.

When you look at each individual part of an opposing force not just in terms of what it can do but also what it needs to survive, what first looked like an impenetrable interlocking wall becomes a rough cloth that someone could begin unraveling by pulling any one of many different threads. As the situation and your analysis both progress, an ideal order of operations might even present itself.
