I'll admit this question may be a bit vague, but a deliberate lack of knowledge is kind of one of the boundary conditions here.
You, dear Worldbuilding Stack Exchange user, have recently been promoted to the head of a three-letter organization (let’s call it the Department of Superhuman Affairs, or DSA for short) which is tasked with controlling and neutralizing supervillain threats. While usually, you’ll have your own team of superheroes stopping the powered psychopath du jour from doing too much damage, they aren’t the most reliable team, and there are certain times that call for a soldier’s expertise rather than that of a superhuman. With that in mind, you have been tasked with equipping and outfitting a team of special forces with the task of killing supervillains. While the individual powerset of a villain is nearly impossible to predict until you actually engage them in combat, they share a few general patterns of behavior:
Supervillains work alone.
While a villainous team-up isn’t unheard of, more often than not the villain in question considers all others beneath them, and will refuse to work with even like-minded criminals.
Supervillains are highly mobile.
The average supervillain doesn’t stand up to much direct firepower, and instead usually prefer to even the odds with some sort of mobility-based ability, be it flight, superhuman speed, teleportation, or something even weirder.
Supervillains prefer urban settings.
A city is a villain’s playground. It’s full of impressive monuments to destroy, buildings to crush, and weaklings to torment/take hostage. You may have to battle a villain outside a metropolitan setting, but the odds are vastly skewed towards the city.
Supervillains and heavy vehicles don’t mix.
Using a helicopter or a tank against a supervillain is almost inevitably a mistake. They’ll usually head straight for it as a show of force, and the amount of collateral damage a tank or helicopter can cause can be immense if it isn’t completely under control..
Supervillains tend to focus on a single power.
Supervillains having more than a single ‘major’ power is nearly unheard of. It would be exceedingly unlikely for a villain to have both pyrokinesis and impossible strength, for example. This means that if a villain is uncreative, their behavior is prone to predictability and repeated strategies.
Supervillains are rarely tactically gifted.
The most intelligent villains are usually the most subtle. Conversely, the most violent and aggressive villains are usually prone to underestimating their enemies, especially if said enemies are composed of ‘puny meatbags’ (their words, not ours.)
Supervillains (for the most part) eschew conventional weaponry.
When you can shoot lightning from your hands, suddenly you lose a lot of interest in firearms. Most villains will rely entirely on their powers for offensive attacks. If a villain uses guns, this likely indicates that their powers rely more on defense or utility than direct attack.
Given modern technology, and assuming money is no object, what equipment and tactics would you utilize to ensure you neutralize the villains with the minimum amount of collateral damage?
