The unexplained concept behind the initial sequence here is that the U.S. Army does NOT lose rifles, under any circumstances — even if they were known to be in a vehicle which was blown up. After they put the fire out, recover the vehicle and remove what’s left of the crew, someone has to go in and find their weapons to make sure they weren’t lost. Then you can write the weapons off of the property book. This gets elaborated on a little bit in the next few pages. The main idea, though, is that this vehicle has been destroyed by an IED — if you’ve got that bit, you can figure out the rest of the story.
For U.S. readers, today is Memorial Day. By all means, use your day off (if you’re lucky enough to have one) to get some work done around your house or relax with your family. I know I did. If you happen to know someone who was killed fighting for this country, take the time to remember them and to rededicate yourself to building a country that is worthy of their sacrifice. If you don’t happen to know anyone who was killed fighting for this country, ask yourself why that is, then take a minute to decorate a lonely grave from the First World War, or the Civil War — one that belongs to someone long forgotten, but to whom we all owe a little bit.
