Lampshaded: "We never seem to hit our targets with these guns, do we Alice?"
Invoked: The man who hired Alice and Bob is The Mole, and gave them guns with dodgy sights and hair-triggers.
Exploited: Steve knows how terrible Alice and Bob are at marksmanship, and uses the opportunity to line up his own shot.
Rather than firing full auto and relying on Bottomless Magazines, Alice and Bob find cover, pick specific targets and aim carefully.
After a few misfired shots, Bob and Alice both attach scopes onto their carbines, allowing them to fire with more precision.
Discussed: "Yes! We shot Steve! And to think, everyone thought we'd just keep missing."
Conversed: "You ever notice how the good guys on television rarely hit their targets? Maybe guns aren't for them..."
Deconstructed: Hitting everywhere but Steve results in severe collateral damage. Hilarity Sues.
Reconstructed: ... Which leads them to travel to a school about firearms, using their poor marksmanship skills usefully, allowing them to show students the dangers of bad accuracy, though their own accuracy is still pretty bad.
Played For Laughs: Everybody's accuracy is bad; many bystanders end up severely wounded and large objects are destroyed.
Played For Drama:
Alice and Bob's sheer inaccuracy with the weapons results in them losing their titles.
Everything but Steve is shot, and he walks by the ravaged landscape completely unharmed.
