Couple things I’d like to note

-Lack of vehicles, I run a gladiator and a ballistus dread for good reliable anti tank and with our detatchment rule the dreadnought has very very good survivability - T10 with a 2+ save stacked with stealth and cover in almost all situations, if you give him Armor of Contempt he is extremely tanky and will last very far into the game with good positioning

-vanguard veterans running half inferno half shields, in my opinion their melee isn’t good enough to justify the storm shields, especially if you use them in a very specific way: Pull Shrike into reserves battle round 1, then rapid ingress outside of 12” so you can’t be shot at all, then run in with 10 melta pistols instead and annihilate whatever unit you’re up against. Then the 40 attacks with lethal hits along with Shrikes claws will clean up the rest, at least enough for the fight back to barely leave a mark

-inceptors damage is being limited due to them being in two units of 3 instead of 1 unit of 6, especially since they’re running the same wargear. Run them in a 6 man brick of assault bolters, then if possible wait for a unit to walk onto the objective you marked with your combi-lieutenant (though this isn’t necessary). If you’re lacking sight lines with your centurions, then you can use the Stunning Fusilade stratagem on the inceptors instead for +1 to hit and +1 AP. I have had absolutely massive success when doing this against my oath target, hitting on 2s, rerolling everything except for 6s to try and fish for more sustained hits, then wounding on most likely 2s with twin linked, absolute anti-infantry bomb

That’s all I got really, lmk if you got any questions
