Detachment theory crafting

Thoughts on Abhuman + siege?

My thought are 3x 6 bulgryns with commissar
- one Commissar takes eager advance - scout 6”
- one Commissar takes Stalwarts Honour - gives “take cover” in addition to the other order
- one Commissar takes Examplar of Duty for 4+ FNP

Wouldn’t this make you bulgryns so much more annoying to deal with?

What is your current go to detachments?
