Global Espionage, Insurgency, Sabotage and counter Terrorism teams

The GEIST teams were formed by the International Peacekeeping Alliance in 2019 in response to the actions of an American Ultranationalist group in China, which managed to evade the Chinese military for three months and forcing the country's national debt to rise to ten times what it was before.

GEIST Training
All GEIST teams were trained to the highest level by their respective governments, not just in combat but in tactical assessment, computer literacy and various sciences, in fact, only 0.02% of applicants even got past the first stage of recruitment and out of those that did, almost 80% proceeded to drop out as they were moulded into the peak of physical and mental perfection.

Eventually, even this wasn't enough. With the introduction of cybernetics and later bionetics, GEIST operatives were honed to the stage that they were stronger, faster and tougher than an enhanced human before then being further enhanced with the latest modifications, which they were then trained in to make them as natural to use as their own limbs.

GEIST Equipment
Much like their training, GEIST operatives were only given the best equipment. Although this changed on an almost monthly basis to keep it at the bleeding edge of technological achievement, by 2050 GEIST teams almost universally carried the following load out;
 * The N-17 Fusion Rifle. The N-17 was an assault rifle powered by a miniature fusion reactor, and which fired pulses of radiation at the target. It came with an alternate fire which fired much like a shotgun loaded with buckshot which was used against tanks, but the primary fire was capable of incapacitating most humans, no matter how well armoured.
 * The X-88 Tactical Sidearm. Despite it's excellent manufacture, the N-17 occasionally broke, and when it did a GEIST operative fell back on the X-88. While it didn't have the fusion reactor of the N-17, the X-88 fired armour-piercing explosive rounds as standard, and could be loaded with gas or even acid rounds as the situation demanded.
 * "Crybaby" Fragmentation Mines. A weapon designed to sow terror and mistrust among defenders, the Crybaby could, after a few minutes of recording, make a sound like the recorded person crying out in pain. When other defenders came to investigate, the mine would go off, killing or maining them. Perhaps most significantly, the Crybaby's fatality rate was designed to be low so survivors could warn other defenders, causing them to leave actual wounded comrades to die for fear of it being a mine.
 * AEGIS Defence Hub. The military had the general populace believing that such fanciful ideas as "force fields" didn't (or preferably couldn't) exist. This was a lie, even before the addition of Invadertech into the mix. Working by identifying and displacing the kinetic power of nearby objects moving above a certain velocity, the AEGIS Defence Hub literally stopped bullets before they could touch the operative.

Infamous GEIST Teams

 * GEIST-1 (English). Led by Elizabeth Jakobs, GEIST-1 was the first team, and had the most terrifying reputation. While all their operations were classified, they are credited as being the team that killed Osama Bin Laden, his severed head reportedly being found pinned to the door of the men's toilet facilities on an American base in the Helmand province of Afghanistan with a combat knife, along with a note simply stating "I'm sorry Princess, your terrorist mastermind is in another castle".
 * GEIST-5 (Spanish). Led by Rodriguez De La Cruz, GEIST-5 specialised in assassination and quiet kills. It is said that a terrorist cell in Madrid was stopped by a GEIST-5 sniper that managed to kill three suicide bombers in three seconds.
 * GEIST-8 (German). Led by Karl Kleitmann, GEIST-8 developed a reputation for demolitions and explosives. While never proved, a group in Munich with suspected ultranationalist dealings found it's entire portfolio of fronts destroyed in a single night and, when they filed for Insurance, found their claims inexplicably denied.
 * GEIST-13 (French). Led by Pierre Belle, GEIST-13 was cursed with a run of bad luck. It had an attrition rate of nearly 84% after only three years of operation and after the soldiers started experimenting with bionetics, the numbers quickly skyrocketed.
