It feels like James Gates wrote this article while power scaling other scifi factions to the Space Marines. I want to address two factions that don't stand a chance.

1) Terran Marines look similar to Space Marines, but while they are tough as nails in the SC universe, they would get stomped in 40K. Their armor and weaponry is child's play to what the Emperor of Mankind used to shield his genetic super soldiers, and even if the armor was comparable, Terran Marines tend to be muscular humans, not genetically enhanced super soldiers. Between training, equipment, and pure biology, Space Marines win, even if outnumbered ten to one.

2) Stormtroopers? Really? Hell, the Guardsmen wouldn't struggle with Stormtroopers. Accuracy jokes aside, we've seem what blasters do to Space Marine armor time and time again. Sure, occasionally guardsman can defeat a Space Marine, bur that's rare. Stormtroopers are not guardsmen: they don't possess the grit to endure that tough of a battle (they've literally run from EWOKS). In no reality do Stormtroopers defeat Space Marines without heavily stacking the odds in their favor, like giving them the Death Star (if we go that route, the Imperium has plenty of doomsday weapons that don't have exhaust port weaknesses).
