All tsu could hear over the comms was the chomping on the gum. "Gaijin." was the only word she could hear from her opponent as a sand storm rolled in. It obscured visibility and made most forms of standard targeting rather useless/difficult.  Then her radar began to go off like crazy, enemy blips pinging everywhere around her. 

This was where a burst from an smg opened up on her gunpla from behind, the sand storm obscuring the gunner.
