Stealth pinning super soldier while double cuffed

They had Stealth in handcuffs. After seeing her move in Smith’s office, he’d used two sets of cuffs. One was latched on her wrists, the other pinched her arms together a few inches above the first set. They’d shackled her legs, too. Polk and Taylor kept her at gunpoint as they marched down the tunnel. The chains rustled and chimed as she shuffled along the hallway.
…
Stealth spun and brought her arms down over Polk’s head. Twin blows to the collarbones stunned him and trapped his neck between the two sets of handcuff chains. She vaulted over him, swung her hips across his shoulders, and dropped to the ground behind the soldier. The cuffs on her wrists pulled tight across his throat. “Release me,” she said, “or I will kill him.”
