Straight: Linda is a smaller than average and good looking Friendly Sniper armed with a large rifle.
Exaggerated: Linda is a teenage girl who fights armed with a gun that's big and scary enough to make Arnie brown his trousers, and spits out massive amounts of bullets, lasers and/or missiles when the trigger is pulled.
Deconstructed: Because of the size disparity, Linda can hardly hold the gun properly, let alone fight the recoil, and thus she's horribly inaccurate, putting bystanders in danger.
Reconstructed: ... So she gets a gun with a built-in bipod, further increasing its size.
Played For Laughs: Linda is armed all the time, even while waiting tables. This leads to some awkward situations. (On the other hand, people never, ever forget to tip her.)
Played For Drama: Something bad happened to Linda recently, and she's taken up arms to protect herself. She's also growing increasingly temperamental and distrusting. Her friends are all worried, but they're too scared of what might happen if they upset her to talk about it.
