Head - Crimson Guard v4
Arms, torso, waist, legs - Cobra Infantry Trooper

Pistol - Marauder Inc.
Headset - Lift-Ticket v3

This trooper is inspired by Cobra communications troopers seen in several early issues of the Marvel comic. Signals are an absolutely vital part of a military or paramilitary force, so Cobra certainly needed some commo guys before the Tele-Vipers arrived in 1985. It needed a basic Cobra uniform but unhelmeted head to allow a removable headset as an accessory. It took a while to find a really good headset - the ones that came with the Eaglehawk are perfect.
