- "Brave foreigners and fearsome soldiers who have left their families to answer King's call. Kyrat has adopted them as her own because she knows that her best interest is in their hearts. May Pagan's light shine upon them all."
- — King Min's Kyrat
Compared to the Royal Army they are much better trained and can withstand more damage before dying. They also make use of better weaponry and vehicles and are more vicious and bloodthirsty than their normal counterparts.
Originally a Triad empire in Hong Kong, they came to Kyrat alongside Pagan Min and Yuma during the Kyrati Civil War and allied themselves with the Royalists in their struggle. After they stormed the palace by force, they killed the distant heir to the throne and betrayed everyone, successfully making a power grab.
They are tasked with guarding key or sensitive locations in Kyrat, such as Pagan, Yuma and the gate to north Kyrat and Durgesh while some are stationed in Shanath Arena as part of the challenge itself. Most recently, however, they've been participating in mining operations and archaeological digs in search of the mythical Shangri-La thangkas in hopes of learning its secrets.
In addition to the mentioned units, the Royal Army has an elite branch called the Royal Guard, which protect sensitive locations in Kyrat, usually in the northern territory. They also guard Pagan Min's palace. The Royal Guard is made up of fewer units than the regular Royal Army, but possess greater firepower, armor, and have superior training.
- Several of their lieutenants are actually undercover CIA assets installed by Willis to spy on Pagan Min and his drug trafficking operation.
- On certain missions (like certain bomb defusal missions), Royal Army troops can be seen in the North working with Royal Guardsmen. Two possible explanations for this are 1, that Pagan Min is running out of seasoned mercenaries, or 2, that these are new recruits to the Guard, who have demonstrated lots of skill in battle, but still, haven't been fully equipped and trained yet.
- Some of its soldiers refused to follow Pagan's order to purge the Royalists and instead fled with them, together with the remaining survivors they went on to form the Golden Path.
- Besides speaking in English, the Royal Guard also speak in a Chinese Dialect such as Cantonese. This may be evidence that they originate from Hong Kong, where the dialect is commonly used. When alarmed, they scold the player Cantonese expletives. When speaking in English, they bear a slight Cantonese accent, common of English-speaking Hong Kongers.
- Despite all having Cantonese accents, some Royal Army soldiers will talk about perhaps one day being introduced into the Royal Guard, suggesting that at least a handful of Royal Guards are Royal Army members who have been shown to be very skilled in battle.
- Some civilians can be overheard complaining about the Royal Guard. In some ways, the people prefer the Royal Army, because "at least they're from Kyrat." This would imply that at least some members of the Royal Guard are from elsewhere, possibly Pagan's men from his days as a gangster in China. This is backed up by their Cantonese accents, and the fact that they sometimes speak in Chinese, specifically Cantonese.
- Royal Guard Snipers, and RPG Shooters have all of their natural teeth replaced with golden teeth. The Royal Guard Charger, however, has rather rotten teeth.
- The Royal Guard also uses body armor, but most enemies can still be killed with a headshot.
- Golden Path Rebels often lose firefights against the Royal Guard, this is likely due to the Royal Guard being able to take more damage and having superior weaponry, such as the P416 assault rifle.
- They can be compared to The Privateers from Far Cry 3, by Weapons, Types/Units and the way they are fighting.
- Some feel torn, or even regretful for some of their actions while working for Pagan Min, or somehow otherwise sympathizing with the citizens of Kyrat, while others seem to love their line of work, and are even slightly sadistic. The strange part is that lines suggesting both viewpoints can be heard from the same guard, in spite of being somewhat conflicting. However, this is likely to be due to programming, rather than some sort of split-personality disorder shared universally amongst the guards.
- Commander version for Royal Guard Assaulter also appears, but in only "Ashes to Ashes" mission in Royal Fortress.
- The Royal Guards along with Mercenaries from Far Cry and Far Cry 2, doesn't speak to death.
When the Royal Guard soldiers are casual, they can be heard saying various things like:
- "I've been in Kyrat so long, I don't know where my real home is anymore."
- "This is the lowest-tech war I've ever been in."
- "The rebels brought this war on themselves."
- "We should burn a village to the ground. That's always fun!"
- "Something I ate isn't sitting well. (a cough)"
- "The rebels deserve their fate."
- "Where's some cloud cover when you need it."
- "I bet that still wakes you up at night."
- "King Min is the beginning and the end."
- "There will be no Orphans when we are done. Min is the father of all."
- "I hear the Americans are developing a new smart rifle, that can let an untrained shooter hit a target from 1000 meters."
- "Saw an ad for a Mark IV Cyber Commando. Don't know what is, but I want it." (Seemingly a reference to Rex Power Colt )

- "Heads up! Ghale is in the AO!"
- "Even your own mother will not recognize you when I'm done."
- "Die Golden Path, die!"
- "You have picked the wrong man to mess with, you stupid Ham Gaa Caan."
- "I got Ghale in my sight!"
- "死冚家鏟!" (Pronounced as "Sei Hai Ham Gaa Caan!" which roughly means "Your whole family all going to die")
- "哇屌!" ( Pronounced as "Wa diu !" which means " Oh fuck !")
- "死仆街!" ( Pronounced as "Sei Pok Gaai" which means "Damn asshole!")

- "死仆街呀!" (Pronounced as "Sei Gaai Ah!" which means "Oh damn fuck!")
