When her father recognizes that the Sentinels need a unit specifically to fight against the Clans, Sheila Arla-Vlata rises to the top of the candidate list for leadership of the Snowbird battalion.

Relevant tropes:
%%* ActionGirl: Quite a few, starting with Sheila herself.
* BadassBoast: "My name is Lance Commander Marion Rhialla. I have drunk more beer, pissed more blood, screwed more people, and killed more Mechwarriors than all of you combined. I am fifty-two years old, tired, and I hate everyone. ''Especially'' nobles."
%%* BadassCrew
%%* BoisterousBruiser: Tooriu Kku
%%* DefectorFromDecadence: Senefa Malthus
%%* DrillSergeantNasty: Marion Rhialla during Snowbird's Interlude.
* ImprobableAge: Most people think Sheila's father is crazy for giving a battalion command to a nineteen-year-old. Maysa Bari is an even better example, being only sixteen as of Snowbird's Interlude and already has eight solo kills.
%%* LittleMissBadass: Maysa Bari
* MamaBear: After catching a saboteur who had gotten Sheila captured, many of the older female members of the Snowbirds (who helped raise Sheila) subject the man to ColdBloodedTorture to make him talk.
