- The Muton Harrier is one of the more unique classes in this mod in terms of how they play. They have three specializations. Broadsider focuses on the use of the Harrier Launcher itself, offering special shots as well as making your standard shots more effective. Pandemonium mainly revolves around thrown greandes and crowd control. Militant makes up for what shortcomings the Harrier has, letting them become solid melee fighters and making them survivable enough to play that role.

- At Squaddie rank, they have the following abilities: Saboteur, Explosives Handler, Cover Me, and Left Cross. In terms of stats, they fall between the Muton Trooper and Muton Hunter/Prowler when it comes to durability, and have slightly less Aim and Defense than a Muton Beleaguer.

- The Muton Harrier does not carry a secondary weapon, and their Harrier Launcher deals Explosion-type damage. Be careful that they don't get stonewalled by enemies with Fortress/Bastion or Blast Padding by branching out into melee skills or keeping them with squadmates. Harriers also do not have Overwatch; they can use Cover Me to assist during an ambush, and can also learn Counting On You to remove Cover Me's cooldown so timing is no longer a factor in its use.

- Unlike every other ranged class in the game, the Muton Harrier does not get a crit chance bonus while flanking. They also do not learn any skills relating to critical hits. Additionally, the Harrier Launcher does not deal crit damage at all.

- The Harrier Launcher deals little damage compared to other primary weapons, but its attacks hit in an area around the primary target, and it ignores cover in its hit chance calculations. Note that it can still miss, and when targeting a group, will roll to hit each individual target. Additionally, the Harrier Launcher cannot benefit from special ammo (they can still equip the ammo, it just won't do anything with a Harrier Launcher primary. I let them keep the ability to equip it in case people want to add the HotLoadAmmo ability to the launchers or give them a different primary for whatever reason), so consider the Plague Grenades or Immolation Grenades skills if you want your Harrier dealing status effects to the enemy. The launcher's range table does not have any positive modifiers (0 is the highest number you're going to get), so if Not Created Equal screws your Aim stat, consider either picking up Against The Odds or specializing in something other than the Harrier Launcher itself.

- Harrier Launchers cannot equip Laser Sights, Hair Triggers, Heavy Barrels, or Experimental Magazines. They can still equip Extended Magazines, Auto Loaders, Speed Loaders, Scopes, and Suppressors.

- When it comes to thrown grenades, the Harrier outshines all other aliens. They are the only Muton with the Blaster Master ability in their main tree, granting them a Muton Grenade, and can also pick up End Of Geneva to remove the cooldown on thrown grenades among other benefits.
