Gatling Man

J.J.'s are large, gun-wielding members of Osmund Saddler's Ganado paramilitary.

Background
Thanks to their truly inhuman strength, they are able to wield Gatling guns, mowing down anything that gets in the way of their target, human or Ganado. They wear red berets and patch over their right eye. If his target is too close he will perform a melee attack with his Gatling gun.

A "J.J." also appeared in the The Mercenaries minigame, as a mini-boss on the Island Base stage.

Like their unique and high ranking brethren (Dr. Salvador, certain high ranking Zealots and certain bosses/mini-bosses found in the game), their bodies do not disintegrate after they are defeated. With the exception of several Ganados with rocket launchers and several mounted Miniguns (most likely AA and anti-infantry) used by Ganados, J.J. is the only Ganado who uses a firearm. Due to his large size, knife attacks will often fail to make him flinch. It is impossible to perform a melee (kick, suplex...etc.) attack on him while he is stunned, but if J.J. is in the way while Leon kicks another stunned ganado he will also get hit and fall down.

J.J. also makes numerous appearances in the Assignment Ada minigame (Ada the Spy in Japan) and is commonly followed by an entourage of Ganados.

Attacks

 * Gatling Fire: J.J. will first swing the weapon to aim when he spots a target, then proceed to spool up the cannon & fire, mowing down anything in it's path (the player, objects and even unlucky Ganados that happen to stumble upon the line of fire). This attack is very damaging and can take off about 25% of health with full health (while 2 shots can kill Ada.) J.J. is fairly slow when he is about to fire which should give the player time to either hide or to take aim at him. If he is shot in the head with a powerful weapon such as a Magnum or a Shotgun, or hit with an explosive, he'll be stunned, and his firing disrupted. J.J. will pause for a few seconds whenever he hits the player but will resume firing shortly.
 * Melee Swing: If the player is too close to J.J., he will perform a melee swing which deals moderate damage and knocks the player back a short distance.

Strategy
One of the best and most efficient ways of killing J.J. is to get to an area where you and him are at a good enough distance, and keep on taking potshots with your Rifle or Magnum when he starts to attempt aiming again. You can do this with whatever weapon you want, but the safest way would be with the Rifle, Magnum or the Infinite Rocket Launcher, since he cannot walk up and hit you when you're far away.

Another effective way to kill him is to run right up to him then shoot him in the face repeatedly using a Shotgun, but this method is harder to pull off unless he is near you.

Mercenaries Only: J.J. can actually kill Militia members for you, in rare cases, J.J. can also kill another J.J.

Trivia

 * His voice clips are identical to those of the Garrador and Super-Salvador.
 * A shot to the head will occasionally knock his beret off, revealing his bald head.
 * Defensively, he is one of the strongest enemies in the game, rivaling the defense of a boss enemy. This is proven by the fact that to kill him with rockets, it takes two, when with most enemies, it only takes one, except for some bosses. However, it takes 3 Handcannon shots to kill him.
 * In Resident Evil 5, there is an enemy named Gatling Gun Majini, which bears a strong resemblance to J.J.
 * The nickname "J.J." is usually given to men who have the common, Spanish name-middle name combo "Juan José" or "José Juan".
 * Unlike the other RE4 and RE5 mini-bosses (they don't disintegrate), J.J. has only ONE variant.
 * Though this may be a game mechanic, J.J. turns around like the torrent miniguns, when shooting.
