>That space marines "don't do dying"
Ah, I see, you're arguing with another guy that exists in your head, not me. Anon, please read this line very slowly and understand what it means "Most of the fighting and dying is done by IG and PDF units".
Space Marines can't sustain the kinds of losses we see in the RTS video games, it logistically does not work, and not every tabletop battle is considered a canon outcome for the same reason. It is highly unusual for space marines to lose an entire company, which is just about what you would deploy on tabletop. Considered the actual scale of warfare in 40k happening across, planets, star systems, and the entire milky way galaxy, for tens of thousands of years, it makes perfect sense that on average, most of the actual fighting the Imperium does isn't with the Space Marines.
Therefore, they pick and choose where they fight, and almost always in theatres where it would be obvious that Imperial Guard and PDF are doing much of the general fighting elsewhere in the backdrop.
To be clear, I'm not saying a single thing about power scaling, per Crunch, many units are on par with Space Marines, but this then means there needs to be an explanation as to why they don't sustain catastrophic losses. The explanation is simple, most of the dying is done by regular humans. You wouldn't post SFs on garrison, or use them as frontliners, you deploy them against strategically important objectives.
All of that said, a non-compliant chapter like the Black Templars who are literally at legion strength can sustain the kinds of losses you'd see in frontline wars, but they're an obvious outlier.
