"General David Petraeus didn’t personally kill Osama bin Laden. Why does “General” Han Solo lead a squad to take out the shield generator? His friends Admiral Akbar and General Calrissian, along with the rest of the rebel command structure, are above, fighting in a short-range gun battle with Imperial Star Destroyers. Captains Kirk and Picard on Star Trek are one-man SEAL teams fighting the enemy whenever they decide to take a break from their real jobs commanding starships, even though they have crews of literally several hundred other people better suited to fighting than the ship’s captain. And while we’re talking about it, what’s going on with space invasions? The last opposed beach landing was at Inchon, over 60 years ago. Even that site was picked to avoid the heart of enemy defenses. Amphibious assaults in World War II were successful, but at a huge price. Helicopter tactics have changed to avoid hot landing zones. With most helicopters running over $20 million a pop, they aren’t thrown out lightly. The same is true for amphibious ships. Who knows how much a spaceship costs? You wouldn’t know by looking at Starship Troopers, Avatar (2009 film), or Star Wars: Episode II. They drop in from space in fragile, helicopter-type vehicles, directly into the enemy defenses. They can literally land anywhere else on the planet, but they choose to land right in front of enemy laser cannon."
