One thing that's always bothered me for a long time in movies & shows (& not just from the US) is that whenever humanity is confronted by a giant monster or spaceship they always attack it with small weapons like 20 or 30mm cannons, unguided rockets, and AA missiles. All things that don't pack much of a boom and they expect them to actually have some kind of effect. Like what's a missile with only a few pounds worth of warhead and whose primary method of causing damage is through fragmentation supposed to do against a monster the size of a good sized building or a spaceship the size of several city blocks? Like in ID4, why did they only send a bunch of fighters after the ship over LA? Why not send up B-52s and B-1s loaded with cruise missiles and launch those from miles out or fly overhead and carpet bomb the hell out of it?
Another annoying thing in movies and shows about the military not shot on an actual military base is how they almost always seem to show people marching or running in formation everywhere? In my experience, outside of boot camp, MOS school, and some special situations, nobody does that. Nobody walks around in squad or platoon sized formations everywhere on base, not even Marine grunts based on 29 Palms where looking for regulation violations is a popular past time amongst staff NCOs. On base people walk around like normal people for the most part, either individually or 1s and 2s. And as for running in formation, that's done, but only during PT which is typically done in the morning and not all times of the day and it's done in a PT uniform and not in full fatigues or what we Marines call boots and utes, boots and cammy pants, but no blouse on top, only a t-shirt. Although, I don't think that dedicated PT uniforms came around until sometime after the '70s and before then boots and utes were the designated PT uniform.
