"Did you ever stare into a dark field at night and imagine that things were moving out there? Well, we Pit-Vipers are really out there, and we're moving toward you."
Intensely trained under the most grueling conditions to be sneaky, ruthless, and persistent, PIT-VIPERS are the stealth evasion and infiltration specialists of the Cobra Ground Forces. Their radar-resistant, magnetically shielded padded uniforms allow them to move silently and undetected even through mine fields and are also efficient in defeating passive thermal detectors. Their helmets contain infrared sensors and fourth generation image intensifiers that provide clear night vision and warnings against trip beams. Their weapons are all suppressed and silenced, firing sub-sonic ammo. Each weapon is made up of non-metallic parts and is shielded against other means of detection. They are conditioned to avoid contact as long as possible to gain the deepest penetration into enemy defenses, but is capable of fierce and efficient response when fired upon.
Before 2003, most night stealth operations were performed by Night-Vipers.
