Rachel

Rachel is a protagonist in Advance Wars: Dual Strike, to the same extent that Jake is. During the beginning of the game, it is clear that she is more advanced that Jake, as she ultimately helps train him, along with others such as Max. She is notably the younger sister of Nell, a character who appeared in the two previous Advance Wars video games that were released on the Game Boy Advance (note: Dual Strike apppeared on the Nintendo DS).
