Armstrong is a dominant force and a versatile player. She can play in the midfield and she can play defense, and regardless of where she is playing, she contributes in largely the same way. She takes her defensive responsibilities seriously, using her physicality to be a defensive force and to be disruptive. She is very comfortable with the ball, and an absolute force when she moves forward and gets into the area. She has great timing and athleticism, so scoring on headers is something she is excellent at, but she has great foot skills and can one-time a ball home or create a goal for herself.
