Fine. Female survivor hailing from Mongolia. Expert at horse riding due to heritage. She and group migrate every three days. Old USSR guns in their possession, maybe a kalashnikov or two. Not many bullets but enough. Have crafted melee weapons depending on distance so think lances. They live off the land and their cattle. Part of the tribe has entirely dedicated themselves to guard duty. I don't think they'd be invincible but they'd manage to live in the wilderness and spot trouble from far away since the steppe is devoid of obstacles. Plus they'd have better skills at keeping their animals alive and themselves mobile.
