Just the fact that you think mass conscription is an advantage really says it all lol
No?
The Imperium makes regular use of everything else too. They have giant landing craft, orbital drop pods, long range guided missiles, armored vehicles, drones, artillery, aerospace support, E-War, mass conscription, magic, and entire worlds to supply it all.
They don't actually lack anything in particular.
The Imperium has these things, but the issue is there is a disconnect between what this implies, and how the Imperium is actually depicted fighting in novels, army codexes, games and visual media, and so on. Which can involve literal Napoleonic infantry squares, a total lack of being able to use supporting fires for anything other than pre-planned barrages before going over the top of trenches (if the author even remembers they exist!), and so on. This isn't all depictions, by any means, and there's stuff which makes the Imperium look more like a modern-ish army, or at least a decent modern war film like Saving Private Ryan, but it is a lot of depictions. So you need to make a judgement about what we choose to throw out or heavily rationalise here.
Even if we err on the side of ignoring the egregiously stupid, and creatively interpreting along the lines of trying to help things make sense wherever possible, I don't think one can reasonably say the Imperium fights wars like a modern US/NATO army. There's too many problematic elements which are more or less omnipresent through their depictions to the point that if you ignore them you are more or less essentially imagining something wholly new, not simply generously interpreting an existing fiction in an attempt to find some coherency. Just looking at the average Imperial Guard platoon, there is no "10 minutes or your JDAM is free!" they can rely on, most of their on-call fire support is regular tube artillery and not incredibly accurate (although there is a decent amount of it), theatres often bog down into literal trench warfare which implies a lack of operational tools for breaking this deadlock, not to mention the literal bayonet charges. Even as rationalised as a "death before dishonour!" or desperation tactic, the last one says something.
There are certainly famous modern armies the Imperial Guard resemble, taking a generous view, but it's probably not the Coalition during Desert Storm, able to simply delete one of the largest armies in the world with airpower before breach through an incredibly dense network of mines, trenches and barricades in a few days, taking more casualties in traffic accidents than combat. It's either various armies of the last century, or something like the Russian army in Ukraine, today. The latter example seems particularly fitting as an analogy because it captures the sheer incongruity of a state which simultaneously has advanced anti-satellite weapons and large quantities of almost every kind of artillery one can conceive of, yet also resorts to sending literal penal battalions to do human wave style assaults in conditions reminiscent of the Western Front or Stalingrad.
The Imperium may have SSTO fighter-bombers and titans, but still seems to need armed teenagers with shovels to actually fight its wars.
Hilariously, reality has shown Trench Warfare making a comeback in heavy combat between peers.
The way Russia and Ukraine both used fortifications is different from how the guard does them, though.
Both Russia and Ukraine used fortified positions to basically force any breakthrough attempt to mass forces, at which point you have a large, easily visible massed assault with a large and vulnerable logistics tail which can be hit by precision and non-precision munitions ranging from Krasnopols and cruise missiles to unguided tube artillery. The fortifications helped bog down the enemy for long enough that they could be accurately attacked by fires.
The Guard doesn't really work the same way, as for them, the fortified position itself is generally portrayed as the most significant source of firepower they have, with indirect fire long-range artillery playing a supporting role rather than being the core of the defensive doctrine.
The issue is more the genre's fault than the Imperium's though.
You see the exact same issue in Star Wars, with the same generic responses. It's a horde of bad writers covered up post-facto explanation of theater shields preventing orbital bombardment from nuking everything and jamming preventing guided missiles and drones from blowing up all infantry.

I mean, I wouldn't call those "post-facto." The jamming is mentioned in the original novelization, and the energy shield is mentioned right away in the second film.It's a horde of bad writers covered up by post-facto explanations of theater shields preventing orbital bombardment from nuking everything and jamming preventing guided missiles and drones from blowing up all infantry and vehicles.
Yes, it's more conventional in 40k's case because it handwaves endless long range precision and bombardment attacks with, 'something something theater shields, something something jamming'.
How's that any different to us though? I mean no we don't have SSTO fighter bombers or building-sized mechs, but in the age of drones and precision-guided munitions, we still need teenagers risking their lives on the ground to fight wars.The Imperium may have SSTO fighter-bombers and titans, but still seems to need armed teenagers with shovels to actually fight its wars.
Do we really want to bring the IoM's aesthetic to modern warfare? Instead of a Predator drone overhead, you've got a winged cyborg baby. The cruise missile that blows up your house is a rocket-propelled coffin guided by a head in a jar. The encrypted data links are just really loud speakers attached to everything and so on.
You have some comic book tier hitters in Age of Sigmar so you can argue that a Bretonnian Bow and Arrow hits somewhere in the same neighbourhood of force as a hammer being swung with enough force to shatter the skull of a continent sized giant.Daemons should be the same in all three settings so you can make the most hilarious powerscaling possible. Yes, that blackpowder great cannon is as strong as a railgun.

These launchers are able to fire a salvo of missiles, each of which is guided by the interred remains of a Chapter Serf.[1]
Honestly, one of the Imperium's issues seems to be quite simply that they encourage specialisation in Imperial Guard regiments in a way that would make many of them good elements in a combined force... and then use the regiments as if they were full armies in their own right anyway. Take the Elysian Drop Troops - extremely good paratroopers by our standards, but you kinda need more than paratroopers even if they've perfected tank drops and by their focus have unusually tight and good relations with the Imperial Navy (eg. the military force in the Imperium that'd be responsible for Desert Storm-like deletion-by-airpower operations).
For some reason I'm pretty sure the shoot it until it dies mentality isn't as simple as you make it out to be.Eh, you can kill a bloodletter by shooting it and daemon incursions are beaten all the time, nothing really to it.
