"Rattler One this is C&C, we've got reports of a resistance cell relocating a protein silo over on the west side of the canyon. King Cobra wants you to check it out."
"Affirmative C&C, Rattler One on the move."
The Serpent Legion:
The UMFL, unlike other union forces, does not consist of citizens of the Sol system. Among their ranks are those who settled the colonies and instead of living a life of starvation and poverty, signed on the dotted line to become military. Companies of "space farmers" turned frame jockeys are the hand of the Union among the colonies.
The Serpent is different.
"We're hardened. We aren't soft like those recruits trying to escape their impoverished shacks. Our hands are forged through battle, hardship, and experience. Every man who wears a serpent on his shoulder earned it in one way or another." - 2nd Lt. Donovan Sykes, Sidewinder Platoon
The Serpent Legion is the chosen elite of the UMFL, hand picked by the ranking members of the Legion. Every member of the steadily growing force has done something to distinguish themselves from the rest of the peasants populating the ranks of the UMFL. Some overcame incredible odds in battle. Others were ruthless in the pursuit of their mission objectives, sacrificing anything that wasn't mission critical to get the job done. Some were outright insane, charging headlong into battle with reckless abandon. Incredible technical aptitude, a mind for tactics, a keen and suspicious eye, every one of these people has a place with the Serpent, it's just a matter of where.
Every candidate is tested rigorously and placed into a role where his or her particular talents will be put to the best use. It takes on average about 4 months for a potential candidate to go from the first rounds of testing to the first day in their new position. During this process they are given the best training money can buy, and access to some of the most advanced gear available.
The Serpent has their own "skunk works" division as well, continuously working on improving and developing weapon and frame designs. Their most recognizable contribution to the Legion is the ST-07X Stealth Chub. The Stealth Chub is completely covered in a rubberized radar absorbent material and has especially designed systems that generate next to no noise (as far as an 18ft tall walking tank is concerned anyways). They are primarily used in small squads which support the main bulk of a company from superior positioning with either long range support fire, targeting information, or hit and run harassment.
Any Orion Militia will tell you when the Serpent's head comes over the horizon, you best find somewhere safe.
