If you're actually serious about war, then military shooters get 99% of it wrong. The US fights wars with unmanned drones, viruses, trade embargoes, and giant bases they airlift to the middle of Afghanistan. More significantly,
So, instead, I think modern military shooters are best understood as Hollywood blockbuster action movies. If we think about it like that, Die Hard takes the geography and materiality of the setting (the mechanics of action) VERY seriously -- in the beginning, Bruce Willis' character takes his shoes off to relax his feet on carpet because he's a stressed-out NYPD cop, but then later he has to walk on broken glass with his bare feet, which has consequences. The movie spends a lot of time on this, and makes sure the line of causality and punchline for the bare feet are all consistent and feel earned... but it spends all of 2 minutes dwelling on the thematic backdrop of terrorism and Japanese-American corporate culture. Bruce Willis is charismatic and human enough for Die Hard to work like this.
