An agent given assignments by the government to handle big threats to interest of world peace or even to help settle a dispute between corporations preferring action over taking it to the main government. The spectre doesn't do negotiations as the authorities have already done that, but simply handles the crisis and cleans up the mess which is another typical job of an infiltrator. Other parts of his job involve securing important data or otherwise things needed by his noble employer whom believes it crucial.
A free living infiltrator who belongs to no one and only lives by his merits of legality making small deals with cartels or authorities while staying professionally anonymous. Sounds easier than it really is since both sides often put much stock into the interest of seemingly minor things which aren't even close to the larger picture of things. Yet both major and minor things catch their interest which is where the smuggler spends a great deal of time trying to disappear shortly after being investigated.
A sort of assassin infiltrator who by contract takes out threats to a corporate boss or takes down rogues just for leisure. Most often these sorts are psychopaths yet are utilized as useful for being trained strictly as assassins.
A special kind of infiltrator whom uses martial as well as psionic abilities to overcome all obstacles which makes them first choice agents for any authority when it comes to choosing. Their ability to escape any hardlock situation is unmatched as they can sense their enemies locations and are intelligent enough to know how to plan their escape. Why else were they chosen to be agents? Some are even made to be ninjas, with as much martial knowledge and psionic power as they wield who would be foolhardy enough to take them on?.
The outfit of an infiltrator is meant for stealth, being effective in any mission given and removing dangerous targets. They wear a helmet for the purpose of having contact with their client and plotting their course both entry and escape and clearly need to have a light amount of armor or risk getting taken down. They are supposed to go up against a small platoon of enemies and in 'Batman' fashion should take them out one by one, they wear mostly plastic to rubble styled armor but don't need a big amount of it, just a belt, shin guards, sprinting boots, gauntlets and gloves and maybe chest armor where the rest is pure leather or spandex making the mission a walk in the park if they do it right.
An Infiltrators Gear
Pistols not meant to harm but to quiet a target who would attempt to intervene or alarm others is still the grade A tool for an infiltrator even as the agency has evolved.
Tough fights where enemies funnel into the room the infiltrator is in, is clearly a call for a rapid fire gun which pack enough round to finish off every man who files into the room they are in.
Part of an infiltrator is a ninja who still uses bladed or brutal weapons for their missions or fights, it makes their fights much quicker this way.
In all situations the infiltrator has a mask since they have more reasons to conceal their identity than others, they can track enemies with it, get quick info with it and can check out the metabolics at any time.
Of all the weapons an infiltrator carries, they like best of all the sniper rifle since they can wipe out tough enemies with it before entering the field!
