Double Subverted: ...But it turns out they missed the target they were actually aiming for, as well.
Everybody's accuracy is bad, and large amounts of bystanders and large objects end up severely wounded.
Nobody cares that they are under heavy fire, because nobody never gets shot in this world.
Everything but Steve is shot, and he walks by the ravaged landscape completely unharmed.
Zig Zagged: Bob and Alice's skills with guns vary.
Averted: Alice and Bob are competent with guns; rather than firing full auto and relying on Bottomless Magazines, they find cover, pick specific targets and aim carefully.
Enforced: The show's producers go The A-Team route; being aware that youths are among the watchers of it, the producers decide to have Alice and Bob purposefully miss Steve, setting up for a bigger clash later on in the episode. See Bloodless Carnage.
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.
Defied: After a few misfired shots, Bob and Alice both attach scopes onto their carbines, allowing them to fire with more precision.
Discussed: "Why don't these guys just try and snipe him out? He wouldn't expect it, and they'd save ammo."
Conversed: "You ever notice how the good guys on television rarely hit their targets? Maybe guns aren't for them..."
Alice and Bob's sheer inaccuracy with the weapons results in them losing their titles.
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.
