Have we any other comparisons with which to judge our general capabilities and successes?
In addition to our campaign successes, the skill levels for our troops is absurdly high.
While the numbers on the military sheet haven't been updated for a while, we do know that we have a +35 on equipment bonus due to the Advanced Wargear we recently equipped our Helguard, Helltroopers, and PDF with. So, based on the current numbers we have available, our troops have this level of skill...
Helguard: +399
Helltroopers: +333
PDF: +294
They also all get these bonuses depending on the situation:
+10 additional bonus against known wildlife of Avernus
+15 additional bonus against Chaos forces
+5 additional bonus against Orks, Dark Eldar, Necrons, Heretics and Psykers, and in melee
+5 additional bonus when fighting in large numbers (20 or more regiments)
+5 addition bonus in sieges
+5 addition bonus against harassment
+5 addition bonus when conducting harassment
+10 addition bonus against insurgents
We also have a militia, composed of 80% of our population. We haven't increased their equipment quality yet, but their bonus is +131.
They also get these situational bonuses:
+8 against known wildlife of Avernus
+4 against Orks, Dark Eldar, Chaos Forces and Necrons
+4 additional bonus when fighting in large numbers (20 or more regiments)
+4 addition bonus in sieges
+4 addition bonus against harassment
+4 addition bonus when conducting harassment
+8 addition bonus against insurgents
Comparing this against the Imperial averages:
PDF: -10-50
Guard: 10-80
Grenadiers: 50-120
Cadians: 110
Stormtroopers: 120-220
with veterans gaining up to +100
So, even ignoring our regular army, our civilian militia is at the level of Stormtroopers, which are the elite soldiers of the Imperium.
Basically, our planet is filled with badasses. We also replaced our primary infantry weapon (the lasgun) with a Dark Age of Technology railgun weapon called Impalers that are better than the Bolters that Space Marines use, and have a lot of other DAoT goodies that make our troops even more deadly.
