In the first photo, a woman already on the ground when attacked defends herself with a sidekick to the attacker's head. In the second photo, a woman uses a palm heel to stop an attacker who tried to grab her. In the third, as an attacker lunged at her knees, a woman delivered a www.dcimpact.org knee to his head. In all three situations, the attacker was not expecting a fight and was caught off-guard with the women's immediate response combined with a loud yell. (Colleen Carpenter, Margaret Vimont, and Martha Thompson took these photos during the final portion of IMPACT self defense courses)
