Decided to my make my own sort of rant on everything i take issue with, with most of the sci fi trends i have seen etc. As a disclaimer i will be mainly comapring it to U.K military doctrine, secondly to the U.S's. (i know most about both of them, and i know compartively little to the rest of the worlds) Right im going to start this with PPE. (personal protective equipment) As far as i know for royal navy doctrine, they have put a large enthisis on fire prevention mesures on ships, more so than apprantly other countries have done. Granted every country has the standard plenty of hoses and fire prevention equipment on board, and has a trained firefighting team for it. But the Royal navy does a 1 week fire safety course, provides flash suits (preventive mesure for munitions), and has oxygen hoods and the like everywhere. Along with what is a global standard of fire teams. So i see in sci fi, ther being comaprively little space PPE, in terms of basically no personal space suits, no communal emrgrency exposure suits, masks etc. Granted some have done it better than others, and i have seen a game give everyone oxygen tanks (and pending server, exposure suits) and there are meant to be sufficent life boats for X amount of the crew/passangers, and also enough flotation devices. So, why in the modenrn world and right now everyone recognised fire as the greatest danger to a modern ship, but we wont in the future recognise fire and exposure as the second greatest to space craft? When we give people floation devices so they can stay floating in water if they fall off a deck etc and also exposure suits for the cold waters. Space is objectively more hostile than the oceans as we can least float ontop and still breath in oceans. If the depicted enviroment is FTL travel, advanced ships etc, you would expect some form of cost effective PPE measures for ships more than life pods. (some dont have them, or have them in terrible places) Second is depicted combat, granted this is more down to doctrine dispute that happens in real life as well. It does largely depend on what you want a military force for, if its for war, you will make diffrent choices to if you want it for law enforcmeent etc, generally speaking there is a mixture of the two, as most countries need warships and patrol ships. The best example i have, no idea if its true or not, was when one of the monarchs spent the royal navies money on several first rate ships for warfare and to impress other nations and to fight other fleets, rather than putting money into ships to patrol english waters and keep pirates etc out, which apprantly lead to some coastal villages and towns being raided and becoming ghost towns overnight due to slavers. (hyberbole im pretty sure, but it makes the point) As for other doctrine issues, WW2 had the aircraft carrier vs battlehship. The franchise that annoys me the most in this regard is star wars. Mainly because the empires fleet is made for war, and is sort of based on WW2 tactics. Instead of patrol ships when they have no enemies, or explained enemies in the films to need a load of capital ships for fighting capital ships for, they needed patrol ships for fighting pirates and criminals. that is the big crutch as the rebels use mainly sub ship craft and didnt start off with many capital ships etc. Is it meant to come off as imperial incompotence or was it a over sight for writing? along with the lack of point defence. I recall adromeda (the one made by the creator of star trek) haveing so-so decent ships in it. they had some ships which could carry X amount of Boats (what i will call vessels that come from a ship, or other paltform) in it which would serve as, both a screen and patrol craft, and strike craft, they were also caapble of being flown remotely, or were autonomous. (truely autonomous i belive, as a AI controlled them) The second one i like for at least so -so realstic space doctrine is Babalyon 5, as they have Boats for patrolling, which also served as strike craft and screens, and every ship apprantly carried at least some and every station for security did. And they are depcited as being used for patrols to intercept pirates and find enemies. Now star trek away teams annoy me, i will let you guess why they annoy me on a realism stance. Anyway i think that hits the high notes and cites some of the series i have seen, anyone else have similar issue with some sci fi and things that just irk you? also this is not a exansive list of my annoyances, just some high notes and as title says focused on warfare.
