Where do I go from here to either keep going to 2500 or chop off the "*" marked Items and make something functional at 2000.Its cool,either way.No IG codex with me,what do you suggest for the HQ+Troops to unlock the Vulture('s)?
Really appreciate any help with this....I like the models but want it to function as well.

Maybe a Primaris Psyker paired up with a platoon. No BRB powers either. That Shroud of his will protect your platoon. Only problem is if he fails a Ld test for a psychic power the commi BLAMS him. Or you could use a command squad to get some orders in.
