Besides being able to use her suit for kicking some serious butt, the Wasp is also heavily skilled in combat. In the comics' storyline, she is trained in unarmed combat by Captain America and how to use her powers during combat by Hank. She is also well-regarded as an amazing leader and strategist. It's because of these skills that Janet is appointed the leader of the Avengers in the comics.
In the movies, Hope can also hold her own in fights with highly skilled opponents. She's actually the one who teaches Scott hand-to-hand combat skills in Ant-Man.
