Let us create the most badass fighting force in the Imperium!
Company Type d10
Maybe that's why Guardsmen look up to them. Because of their close ties to the Navigators they always have access to a fast voidship to get them to a crisis zone. So Guardsmen are always getting saved by the timely arrival of these fellows when times like dire, and they sneak in to blow up enemy fortifications that allow the regular Guards or PDF to actually get the real glory of battle.
Elite Tacticool desert grenadiers who are allies with the Navis Noblite and are stealthy.
So these chaps show up fast, have good naval support, blow shit up, come from the desert, and are Heroic as fuck despite being operators who operate operationally. Like Seal Team 6.
Just to be different I vote for something like the Persian Immortals - an elite army of faceless men, one dies another takes his place, so they appear to never be defeated. Their enemies are the barbaric (greek) Ork hordes.
>one names, another one takes his place
Let's be fair, literally nobody that these guys would fight would give a fuck about that. They wouldn't be wasted on attrition warfare or really obvious/demoralising hit and run tactics, but rather for wrecking shit without being seen.
So we've got unorthodox tribals that somehow still got on the good side of sisters, with their own stormtrooper regiment.
I'm guessing the stormtroopers take advantage of charging, tactic-less tribal guardsmen to set up ambushes and sneak attacks while the enemy are distracted. It's not seen as using the guardsmen, since they legitimately do lesson casualties by striking down the enemy with their superior weapons and skills, giving a chance for the tribal guardsmen to put their numbers and limited training to good use.
Tribal doesnt have to mean dumb anon.
The Tanith were Celts, and I'm honestly not sure if what level of tech they were at.
Either way, I find the contrast between the Stormtroopers and the IG they're recruited from a lot more fun than 'they're both sneeki breeki.'
Some guard regiments have higher ranking veterans like grenadiers, or the worlds they recruit from are able to raise their own stormtroopers to fight alongside their regiments. It's not an exclusively Schola Progenium thing like with the Tempestus Scions - who are organized into their own distinct regiments in their own little organization that's distinct from Guardsmen.
Basically, it's the best way GW could have let the new Scions fluff meld in with the old stormtrooper fluff without breaking either of the two.
Not quite. Put simply storm troopers/scions and grenadiers are different things. Storm troopers were never the same as grenadiers, even before they became scions they were centrally trained and controlled, not directly part of any regiment. Grenadiers are and were the line guardsmen equivalent of storm troopers, equipped and to some extent trained like storm troopers but used to fight directly alongside guardsmen instead of as auxiliaries.
To put it this way lets say you wanted to be a soldier who uses a hotshot lasgun and wears carapace armour, there are four ways to do that.
1. Buy your own shit or have someone buy it for you because you work for an inqusitor or rogue trader or something.
2. Be an orphan taken in by the Schola and become a storm trooper/scion.
3. Be a guardsman who is a cut above the rest and pulled from his unit to be placed in an elite grenadier company or regiment (akin to Krieg Grenadiers or Cadian Kasrkin).
4. Be a skilled man who has been sponsored to join the Schola by an inquisitor so you can be trained alongside teenagers despite being a 20-50 year old man. Get some nice gear and be sent to serve your inquisitor.
While a grenadier might be on par with a tempestus scion they aren't quite the same thing.
It's not a definite source of recruits? Lots of regiments would rather keep their vets if they can, and there can be only so many IG vets since a regiment has only so many men in it, and only so many survive to be good enough to be considered veteran. And regiments don't often stick around in one place after a campaign.
