M4A1 is not that reliable but gets the job done, she is considered a very important doll but she doesn't think so, she is a lil depressed and anti social cuz of wut happened to M16A1 (she turned to Sangvis), she likes to be alone but not alone to the sence where she looses everyone she loves she already lost most, she is very over protective and puts others first and doesn't really care about herself she can't risk anymore deaths, shes hides her sadness to be perfect for the commander.
