A little back-story and character profile on my two characters. Both already posted, this is just a little expansion.
#1: Warclaw
Mech of Choice: JR7-31P Rattlesnake
Preferred assignment: Headhunting/Decapitation Strikes
Cold-hearted bastard, Assassin in a mech, evil son-of-a-bitch, Ruthless mercenary, and sneaky bugger. All these things and more he's been called. He prefers to think of himself as efficient and precise. He will not shrink from whatever it takes to accomplish his mission, and take out his target. BUT, neither will he create destruction and death where it is not necessary. For example, he might pass by a burning building, leaving the occupants to their fate, if taking the time to help would endanger the mission, and yet take care not to step on non-combatants (Cooks, mechanics, and such) while withdrawing in the chaos following an attack. (The fact that he's most likely left multiple targeting beacons in the camp not withstanding. If they are fools enough to waste the chance he's given them, so be it.)
Known for appearing in places thought inaccessible, Warclaw has been known to travel for kilometers along the bottom of a lake, so as to avoid detection until he struck.
Previous commanders found that while he can follow detailed orders, he is most effective when given an objective and allowed leeway in his methods of accomplishing it.
Somewhat of a loner by nature, Warclaw has never sought to lead others, reasoning that few could follow him on his missions, and even less would want to.
A pragmatic man, and realistic as to his likely eventual fate, he doesn't dwell very much on the future. He knows that someday he's going to get caught and probably killed on one of his jobs, but until then, he reasons that every headhunting mission he pulls off, even if he's taken out in the process, means a major advantage for his side, at the cost of a single light mech and pilot at the most.
2: Gabriel Thorne, Knight-Errant of the Order of Randis.
Mech of Choice: PX-3R Phoenix
Preferred Assignment: Pirate Hunting
If you took an idealized character profile from a tri-vid noble knight, you'd have Gabriel. Honorable, honest, brave, daring, committed, and kind. However, unlike many of the Tri-vid knights, Gabriel is nobody's fool, and while he is completely devoted to the Code of Randis, he also understands that the Code doesn't cover every situation, and in many cases is better used as a guideline to where the boundaries of honor lie.
Gabriel believes bone-deep in living his honor and code, not just giving lip service. That being the case, he sees his greatest duty in placing himself between innocents/non-combatants and any that would harm them. For that reason, he spends much of his time bouncing from unit to unit, one contract to the next, taking work wherever he feels he can do the most good (and spread the word of Randis). He has spent much of recent history on an extended pirate hunting contract in the deep periphery, where his ancient mech is still potent enough to serve. Back in the Inner Sphere, with the newer designs and technology coming onto the market, he has been relegated to rear area defense work, mostly guarding the medical units.
