A Regular Mook is the standard opponent and the most common. Toting an assault rifle, he'll lay down fire when he detects a bro until one of them dies. He can be parachuted and spawn from a Mook Door. Despite their low rate of fire, they are one of the more common sources of deaths for anyone who does not pay attention to the "!" symbol.
The Suicide Mook will search for bros, charge them and detonate. This can be a game-changer in tight quarters. It's best to knock these mooks back from a distance so as not to get caught in the explosion. They will detonate shortly after they are dead. He can be parachuted and spawn from a Mook Door. His explosions is a double-edged sword and deals damage to destructible terrain/other enemies.
A Riot Shield Mook hides behind his riot shield and reflect them. He can be very helpful to stop bullets from hitting other Mooks alike.
The Shield does not protect against splash damage and melee attacks. It also cannot shield him from the back. Throwing him will also remove the shield. Taking too much damage in a short session can also cause him to abandon the shield.
If he is not killed and the shield is thrown off, he will be unable to retaliate due to being unarmed.
A Bruiser can take more damage and spool up a minigun. They are very dangerous and can be tricky to combat. Unlike regular mooks, Bruiser attacks seem to deal less damage per single round (when the rounds are returned to him with special abilities), but is still instant death to players. Bruisers tend to operate in bursts constantly, and for a short while after a player disappears from his line of sight.
A Scout Mook looks for bros and after detecting one, runs around alerting other hostile units of their presence. And will also use nearby alarms that can potentially summon endless amounts of mooks (unless turned off), it's best to kill them quickly.
Unlike most enemies, Scout Mooks have no depth perception and can often fall to their deaths.
Scouts will also not detect corpses blood or anything that's normally incriminating like other mooks.
He will often yell "Broforce" when spotting a player, making him one of the only few enemies with legible speech.
An attack dog is a melee enemy that will jump into nearby bros. It will feed on a corpse when it finds one until its destruction and will then howl before becoming a bigger and stronger version: The Super-Size-Me Dog
The super-size-me dog basically has more health than a regular dog, but is otherwise similar.
The attack dog is drawn to the sound of gunfire, and will automatically detect a bro if it hears a shot. They are extremely deadly and agile, yet can be killed easily if the player was alert.
An Armored Mook is a mook in a Mech suit, which is almost impossible to destroy and fires devastating bullet storms in short bursts. The occupant is weak to falls. Bros can jump on him. After his death(or, simply press the melee button to hijack which kills the mook inside), it is possible to use the armor suit to the player's advantage.

A Grenadier Mook will toss grenades in a bro's direction, and also drop one when they die. Each time one of their corpses is hit, a grenade is dropped from it. His grenades can be thrown back by pressing the melee attack near them. They have infinite grenades.
A Bazooka Mook will launch destroyable rockets to bros. Their rockets are homing, making them very dangerous.
The rocket can be destroyed if it takes enough damage mid-air, and the explosion harms both players and enemies alike.
A Ninja Mook is an opponent who lays down until a bro gets close enough. It can be hidden by a Foreground Bush Doodad Or Alien Fronds but a pixel can still be seen. They will behave like a basic mook once leaped out.
A Jetpack Mook is an opponent who hovers if seeing a bro. Upon death, his jetpack acts as a Propane Tank going to the direction he's facing before exploding. If the mook hits a wall though he will bounce or stop moving. They have the same fire rate as a Mook.
Skinned mooks can be found via the level editor or skinning someone up with Brodators wrist blade
They can be hanged to the ceiling or placed on the floor they can be eaten by Attack dogs
They are pretty nice scenery for desecrated villages
In hell they will attempt to jump on your back if they are hung they will be just stuck there though they will notice you
