"Good enough," he replies, half ego and half honesty, because what he has in his hands is far from his standard, preferred gear. But he's gotten off a few practice shots, enough to start rangefinding, and enough to know how much he'll be able to manage the second Theta translates over the tactical info and he just knows where the enemy combatants are, even beyond the basic information he can tug together from standard visual and thermals. He smiles, half to himself, reaching back to his hip to touch and confirm that he still has one of the stun grenades he'd grabbed on his way through the armory. "-not sure I'll need it, though."

Time to test an idea.

Around the corner, barrel up, two quick shots of the unfamiliar stun rounds, which don't hit but at least force a dodge back and give him some breathing room. Return fire he knows is coming, more shots to herd them back and he knows that Theta knows what's coming, but calls the play anyway.

"Going long, Theta, guide me in."

"Okay!" he calls back, in the familiar cadence of brain-and-ear-and-voice speed, counterpoint to the micro-adjustments to objective and aim as he guides the grenade so it rebounds off a wall and into the clustered mass of hostiles, times to the milisecond the now! that sets off North and his shield with just enough lead time for his nerves to jump to action. After the hesitance of even speaking to Cortana, it's quick and fearless and there's a firework burst of satisfaction when the flashbang goes off inside the closed bubble of the shield, rebounding and amplifying the force against the unlucky handful trapped inside.
