Inceptor

It's like John Wick and a Spring Boot had a baby.

Not to be confused with the Intercessor Squad nor with the actual Space Marine Chapter Inceptors (Whoever came up with these names needs to get their balls kicked), another unit from the Primaris Marines that just so happens to share the same similar sounding names. Seriously try saying Intercessor and then Inceptor repeatedly in a rapid session. You will get your tongue tied.

Inceptors AKA those guys with the ridiculous shoe shovels, are the Primaris' equivalent of Seraphim Squads. Despite their outward appearances, they are NOT related by function, to the Space Marine Assault Squad as they are more situated towards quick hit-and-runs and surprise ambushes rather then heads-on assault charges and CQC combat. Ironically, this makes them closer to a Space Marine Bike Squad.

Despite lacking any form of close combat weapons (For now at least), Inceptors are still relatively decent at fighting off enemies at close range via the good old tactic on turning yourself into a living rocket. Of course, since they lack any form of decent CQC weapons, they would crumple like a wet tissue when it comes to facing off against melee-orientated troops such as Nobs, Genestealers or Emperor-forbid, Khorne Berserkers.

In a nutshell. They are basically Primaris Seraphims. Seriously they act like one. Alternatively, one could see them as Jump Pack equipped Aggressors, given their use of Gravis Armor and dual weapons. More like Primaris version of XV-8 Crisis Battlesuit, really.

In current fluff, Inceptors often deploy from orbit, drop through atmospheric re-entry emulating missiles or debris, and smash down on the enemy's heads and annihilate anti-air/armor/etc. for their brothers slamming down after them to kick ass.

Equipment

An average by-the-books Inceptor, who is usually part of a Squad of three to six, wears the signature and skubby Mark X Gravis Pattern variant of Mark X Tacticus Power Armour. The Inceptors are equipped with the notorious shoe shovels officially called the Servo-equipped boot-plates which allow Inceptor Squads to survive landings at intense speeds, and provide extra boost when they jump from the ground. It is like a combination of the Long Fall Boots from Portal and Inspector Gadget's Spring Legs. Inceptors are often paired with squads attacking by Drop Pods and are the perfect troops to blast out a beachhead and then provide fire support to keep it clear.

Inceptors usually wield twin Assault Bolters into combat, which are basically Heavy Bolters, akimbo style. Yep, it is as ridiculous as it sounds. Somehow the Assault Bolters have some recoil-compensating bullshit technology that allows a steady grip on firing these giant Bolt rounds without dislocating the marine's joints off.

They can also wield twin Plasma Exterminators which are basically pint-sized Plasma Cannons for twice the fun. Seriously, you thought the Assault Bolter was ridiculous? Assault Exterminators would say Fuck the Noise and would make your power armor bend over.
