They need to be identified... ribbons are given not just for combat time but also for some special, non-combat achievement. Maybe she qualified as a sharp shooter 3 years in a row and that may have given her 2-3 ribbons. Maybe she ran faster than anyone in her age group during the PT tests. You simply cannot know. Find out if she released her military records with the DoD and get a copy of her DD214. Every ribbon and medal and achievement will be listed there.
Dems usually don’t release their DD214s.
