>>190501Posey's Dreads have a 40 ft fly speed with good maneuverability. They have +4 Racial bonus to spot and listen. They should easily be able to find the battlefield from the direction of the gunfire.
She could order her Dreads to fire at the GRU, to harass them and draw attention away from Cavalier and Kira, which would give them cover to escape. They may also enter melee and use their Frightful Presence to weaken GRU morale.
If they're destroyed, I don't mind. They cost 1050 gp to produce, but I got them for free from a demon so it's a small loss on my part to defend the party and get past this encounter. I got some good mileage out of them this adventure.
Just say the words and I will send them out. I don't want to steal anypony's thunder unless they ask for it.
If you would rather Posey order them to obey Kira or Cavalier's commands, their stats are here:

Frightful Presence (Su): Any creature with 2 or fewer HD within 30 feet of a dread must succeed on a DC 12 Will save or become shaken for 2d6 rounds. A creature that is already shaken (by the frightful presence of a second dread, for example) becomes frightened instead. If the creature is already frightened, the dread's frightful presence produces no further effect. A successful save renders the creature immune to that dread's frightful presence for 24 hours. Frightful presence is a mind-affecting fear effect. The save DC is Wisdom-based.
Weapon Use (Ex): A Medium dread can use weapons sized for Medium creatures with no penalty, since its arms are roughly the same size as those of a Medium humanoid.
Skills: A dread has a +4 racial bonus on Listen and Spot checks.
Dreads attack relentlessly as ordered by their creator. The necromantic magic used in their creation surrounds them with an aura of supernatural fear.
A dread is a pair of animated skeletal arms created for use as an undead guardian. Like a skeleton, it is a mindless automaton that obeys the commands of its master, but it also carries an aura of supernatural terror. Each of a dread's arms is 2 to 4 feet long and weighs 10 to 40 pounds.
