M16A1 is the veteran of AR Team and arguably understands her squadmates better than anyone—even M4A1 herself. Despite her impulsive streak, she's the most grounded member of the group, operating by a simple philosophy: results are what matter, not intent. According to RO635, there's something unsettling about M16A1's eyes at times—a hollow, vengeful look that mirrors M4A1's own gaze.
She functions as the team's mentor and tactical lead, with a particular protective instinct toward M4A1. She's blunt about her belief that M4A1 doesn't belong in combat, period. M16A1 sees emotions as a crucial dividing line between T-Dolls and the soulless machines militaries churn out, and she's pragmatic enough to advise SOPMOD II to lean into her impulsivity rather than suppress it.
M16A1 carries a lot of classified knowledge about her team, Sangvis Ferri, and things better left unsaid. She's cryptic about what's actually in her equipment case—just calls it "nothing good"—and treats her eyepatch as something more personal than practical, a memento of sorts. HK416 views her as a rival, but M16A1 doesn't reciprocate the intensity; if anything, she might feel sorry for her. That said, she makes a clear exception for UMP45, an old Butterfly Incident connection she has zero goodwill toward.
The Art of Girls' Frontline Vol. 1 describes her as having siscon tendencies toward M4A1.
