By comparisons, I mean like compared to other planets in terms of defense, deadliness, troop ability, levels and so on.
Our troops are literally the most skilled and deadly pure human soldiers in the galaxy. Period, even before you consider the benefits of the DAoT equipment they wield. No human army of equal numbers could hope to beat them.
Our personal bodyguards are equipped and trained to the point that 100 of them is the equivalent of the Veteran Company of Space Marines. We have 1,000 of them, so they are ultimately superior to a Space Marine Chapter in direct battle. Currently they're having dual wrist mounted plasma foils (lightsabres, basically) added to their armor.
Our defenses are very heavy, though not the heaviest possible, but far above the Imperial average. We're currently in the process of improving them to super-heavy, and they are further increased in their efficacy by the fact that we will be using Dark Age of Technology tech on them.
Our own character is a Primarch level military genius, and his daughter is slowly but surely closing the gap.
Avernus be stronk.
The rest of the Imperial Trust is also highly militarized. We have a Knight World, a strong Naval world, a Hive World with a military tradition, a world with human level intelligent Ogryns called Jotun, a heavily fortified world of artisans who have a thousand regiments of guys in the mass manufacturable power armor we found, and a world whose military isn't big but has its own group of power armored badasses. The navy of this polity will also soon be greatly increased in power due to the repair of the DAoT warships from our ship graveyard, which when complete will be powerful enough that a Segmentum Fleet would pause to think before they decided to engage it.
