The only way to calm your nerves in that environment was to marvel at the insane amount of firepower available to the Americans and hope that that changed the equation somehow. They have a huge shoulder-fired rocket called a Javelin, for example, that can be steered into the window of a speeding car half a mile away. Each Javelin round costs $80,000, and the idea that it’s fired by a guy who doesn’t make that in a year at a guy who doesn’t make that in a lifetime is somehow so outrageous it almost makes the war seem winnable.
