Why would they? They're just here to punch the clock. Invading planets nine to five, then check out and relax. And you know what? If you get killed, you get a vacation. Of course, it must not be obvious that you got killed on purpose - so you just do the job you got, exactly according to spec, without ever thinking about anything new. The managers don't ...

All that gold makes gold virtually worthless so people would put it to practical use like construction. The Pantheon is held together with iron bars coated in lead to slow down corrosion. You could get better protection coating iron in gold. You can coat roofs in gold leaf for excellent waterproofing. The ancient Romans used lead pipes for water. Gold ...

I began to plan out various tactics and such, when I realized it was all for naught. Let's suppose they breach the perimiter of the base. They will soon face an unsolvable problem. They don't have heavy weapons or explosives. A base, supposedly high-tech, important and secretive will be built with nuclear bunker specifications in mind. The base personnel ...

Use their attraction towards magic to drown them into poop It's too exhausting to renew all these expensive defense mechanisms. There is one resource the kingdom will never run out of: poop. Let your drowning tank refills itself, as monsters are irresistibly lured toward the huge pile of magical artifacts you placed at the bottom of it. It is actually a ...

Assuming that the object is to protect earth, and not just hide away when the aliens come... Join the Department of Extraterrestrial Defense The Department was founded in the sixties, at the same time as the project to create a psychic supersoldier using LSD. Currently it consists of one insane bearded guy, in the 22nd basement level of the Pentagon. ...

The zombies are idiots. Zombies can attack or defend, but they can't attack intelligently, and they can only do both at once with a lot of attention from the sorcerer. In a fight, a skilled fighter (person A) is constantly assessing their opponent(person B) or opponents. Person A's goal is to hurt person B without being hurt in return, so person A puts a ...

They do not know what the tactics were Combat is a horribly confusing environment to be in. No one has the full picture of exactly what happened afterwards - recollections of individuals are contradictory and have been shown to be incorrect when compared to film evidence. It is only in modern FPS video games that kill-cam views show you how you "died". ...

There are a couple good answers already about how Paul can help the world prepare by sharing knowledge, or advancing technology. But if he is really prepared to consider any option, to take any action, there are at least a couple more options he should consider, whether or not he actually decides on using them. Take up Super-villainy Honestly, there is ...

The Power of Sports is useful, But Overstated I am a combat veteran of two wars and I found competitive sports useful to provide a distraction and work off excess anxiety and restlessness, but frankly there never was an Oscar worthy moment where the power of sportsmanship and football suddenly made all my problems go away. Military indoctrination, mental ...

Because they're winning Demons want to corrupt. They want to take good things and twist them. Humans, wrongly, believe that the demons are trying to conquer Midgaard, but that's not their aim. They want to keep the people of Midgaard in a state of fear, they want them to prioritise war and fighting over creation, art, and being good to one another. They ...

Castles were useful for a certain type of defensive warfare. They allow you to project power over an area with a relatively small but immobile force. You could consider them to be primarily a delaying tactic, designed to hold up the enemy until such time as a significant force could be brought in. A good castle can be the deciding factor when a smaller ...

Not all threats are for violence. Countries often threaten one another with sanctions without going to war. To intimidate another group you just need the threat of an action which is detrimental to them, not necessarily violent. Use your technological superiority to take their resources right out of their hands, consume a nearby plant with your mining, or ...

why invade at all? Most structures of a civilisation are probably going to be on a surface. It is, after all, more difficult to build underground than on a surface. That means that most items of value can be simply blasted from above. But you might not want to blast them from orbit because these items might also be of value to you. You might want to avoid ...

There are a lot of bad answers here that mainly seem to come out of a few pervasive myths about European colonialism. There is no need to go around killing the natives at a ratio sufficient to match their relative population. There is barely any need to fight the natives at all. Naval or ranged bombardment is neither necessary nor all that effective in the ...

The primary reason why gold is so valuable is because of scarcity. Once you eliminate scarcity there are many uses that gold can be put to. Chemically it is highly nonreactive making it a good fit for containing reactive materials and foodstuffs, and anywhere that you want a durable cladding that doesn't require much strength. It conducts heat well making ...

32 attackers, 221,968 distractions Coordinating a quarter of a million young men via Facebook event is a nightmare I wouldn't wish on my worst enemy. Coordinating search and rescue for a quarter of a million men stranded in the desert and dying of thirst is even worse. I fully expect the national guard to be deployed simply to deal with the humanitarian ...

Rule #1 of Storm Area 51 Club: Don’t talk about Storm Area 51 Club (SA51C) Secrecy and Surprise are important strategies in any act of Civil Disobedience Rule #2 of SA51C: Don’t carry weapons of any type. 1 rifleman can shoot a thousand civilians running across the desert. And, Close Air Support from a Spectre Gunship will ruin your day. But it ...

Zombies have no sense of self-preservation. If you tell a zombie to walk to the castle, they'll do it, even if there's a moat in the way. Or caltrops. Or fire. There is no difference between the actions of a normal zombie and a zombie on fire, unless given a specific order otherwise. A bleeding warrior will stop and get bandaged; a bleeding zombie will keep ...

It is already too late. Any decision you make will either be a) one you have been gently guided towards by a posthuman superintelligence (with or without your realisation of this fact) or b) one that the posthumans have noted and decided to be entirely compatible with their other aims. You can't wriggle out from under the unblinking omnidirectional gaze of ...

There are some deep contradictions here, which probably have to be resolved before a plausible answer can be provided. No Instinctive Drives The first thing we need to establish is that a computer would not only have a moral code, it would lack all the sci-fi tropes of survival instinct, etc. so it's unlikely to kill its creator in an attempt to survive, ...

Medieval sieges had two components to them: Starve them out. We're talking medieval technologies, so farming isn't anywhere what it is today...more land was needed to feed people. If there was an ability to gain food and water during a siege by the defender, this becomes a pretty useless tactic honestly. As an extension to this, there is little to ...

I would like the reaction to the appearance of one of my nations navies to elicit a feeling of dread or fear Some answers have suggested sanctions and other such "pacifistic" approaches. I don't like these approaches, but you can try them. Just remember that Germany was France's #1 trading partner before WWI. My approach would be to be harmless but still ...

As a wily local Baron, I'm skilled in intrigue and deception. As a skilled Feudal warrior myself, I recognize the difference between offensive and defensive weapons and tactics, the proper uses of different weapons, and defenses against those weapons. I'll quickly recognize that these are not gods carrying magic wands. Those are men carrying weapons, ...

Mines could work if we stretch the definition of a mine. The problem with space is... it is big really big you just won't believe how vastly, hugely, mindbogglingly big it is I mean, you may think it's a long way down the street to the chemist, but that's just peanuts to space. Listen... So our mines can't be stationary as they'll hardly ever be in the ...

TLDR: It's a matter of cost: building castles costs a lot, but assieging a castle also costs a lot. However, you need to control the castle in order to secure your supply line and/or control the region. As to the first point: sure I can escape into my eagles nest and be relatively safe as long as supplies last. But unless I have a sizable force at my ...

Every good hero has a fatal flaw. Even Superman has kryptonite, and is arguably kindof a coward. For your speedster, maybe he's not very good at forward-thinking. The non-speedster only has to set up some bait and swing his bat -- the speedster hits the bat every time, and at those speeds, the blow does a lot of damage. For that matter, your speedster can'...

I would argue that the modern day military would have to monumentally screw up in order to not wipe the floor with the 1600s era military, no matter how great the numerical disparity. Chances are they would not even have to meet the enemy in the field. All it would take is a show of force with a flight of aircraft bombing their forts and government ...

A lot depends on the skill and morale of both armies and the tactics employed. There have certainly been many cases in history where a technologically superior army crushed a technologically inferior one. The European conquest of the Americas come to mind. But bear in mind that it's not a given. When the Spanish under Magellan landed in the Philippines and ...

In medieval times and earlier, in any battle of trained units versus armed farmers the trained units indeed had fair odds of beating engagements that were 10:1. Zombies are not simply poorly trained units. They are completely untrained, disorganized, unled, and literally brain-dead units. Zombies don't suspect or prepare for an ambush in a spot that's ...

How to defend against the Spanish (Y'Ang) Armada 1. Have spies find out when the Y'Ang Armada is setting sail. This would make the situation a lot easier. In the case of the Spanish Armada, the fact that the Pope granted the Spanish soldiers indulgences and allowed King Phillip of Spain to collect a crusade tax was kind of a dead giveaway. The logistical ...
