Lack of attention to detail kills......suspension of disbelief. Especially in MilSciFi. When you get the names of the tanks and tactics right....but leave the audience wondering why the hell your characters are doing what they do....you've missed something. Case in point...Battle: Los Angeles (2011). It makes a good example, since it combines all kinds of poor detail work. #1: The military shows up fast. The Marines (and significant National Guard and Air Force ground units) deploy to LA (from Pendleton and 29 Palms) within what appears to be an hour or so. Yes and no. Yes, you'd get a small group (Assess and Eval teams, and Leader's Recon/Forward CP could get there as fast as you can stuff a dozen guys onto a chopper and fly) into the AO really quick....but nothing that would be shooting. To get an Infantry battalion onto transport (much less roll/fly/etc out to the AO) from a cold start (finding all your Officers and NCOs, who mostly live off-post and may be working on different areas of the Post, drawing weapons, ammo, ordnance....OPORDs...comms check...map recon...,etc)....could be as much a 6 hours. We don't sit around our Forts, Bases, and Stations waiting to deploy into combat. An HBCT might have half its vehicles disassembled for maintenance. Ditto with Fighter Wings, Helo squadrons, etc. We aren't in a combat ready posture when we are at home. Movies like Cloverfield do this, too. With the Army somehow getting into NYC within a couple of hours of the Monster wading ashore. Nope (closest Army combat units are at Ft. Drum, on the other end of the State). Nor can National Guard units mobilize that quick. They take even longer than Regular units, from a standing start (as the troops and leaders might be spread across half a state, with their crew-served and heavy gear/combat systems stored elsewhere). They do this because they can't be bothered (or just can't) shaping the story to feel like time is passing, so everything in the world happens in a few hours. #2: Colonel Squad Leader. The entire leadership of a unit is constantly accompanying/leading a small subset of that unit. Lt. Martinez and SSGT Nance (the Platoon Sergeant, 2IC) both go with one Squad (and a machine gun team that never actually appears). Never mind that this dispenses with the entire reason you have both a PL and a PSG (so that you can split the Platoon and still have a leadership cell with each part)......they both go with one squad....while the other 3/4 of the Platoon is never seen again. They do this because they can't handle (and don't think the audience can handle) more than a handful of people onscreen at any one time. Not speaking characters, just moving bodies. #3: The General sweeps the floor. Important people doing trivial tasks. Both of the Platoon's leaders (Martinez and Nance) follow one squad on a civilian evacuation mission. Meanwhile, the now-leaderless Platoon is actually doing the fighting (and interfacing over a 2-echelon jump to Company, with a Squad Leader having to step up). Hollywood likes to have important people (with important-sounding titles) on the job, because less-important people couldn't get away with or take as much on themselves. #4: Hollywood Priorities/Must. Save. The. Goat! The US Armed Forces are losing the battle for Los Angeles (California) to an alien amphibian invasion force.......and the priority is evacuating a few hundred civilians from behind enemy lines. To the point that they are sending out entire squads from what is explicitly a crumbling defensive line, in the hope of guiding these lost civvies to safety. Don't make me fucking laugh. Civilians (below the scale of "Population of California") would be the bottom-most priority. The uppermost priority would be trading space for time and preserving the combat forces. They do this because they can't think of a way to make a "combat-combat" (versus combat interspersed with a lot of noncombat social/interpersonal drama) story interesting for an audience...which shows how bankrupt the screenwriters and directors are. I don't demand hard realism from my Hollywood scifi fare......but I do expect them not to simply throw their hands up in despair and flatly impose blatantly unrealistic actions because they couldn't think of any other way to create tension. A medical drama where the entire ER trauma team wastes an hour removing a thumbtack from a puppy's paw.....while the victims of a schoolbus rollover slowly die in triage....would be just as bad as some of the stuff Hollywood likes to derail (scifi) war movies with. Opinions? Brickbats?
