Can I sue Xerox if they "RIF'd" me after I had to leave for military service

March 26, 2014 I was pulled out of the middle of my training by my manager and brought into a small office with a HR rep. I was told that I was being RIF'd along with another individual on the team. When I inquired about how the decision was made, I was told that it was based off of seniority and how well a rep was doing. Based on my scores and instructors, I was told that I was top of the class and able to adapt as well as understand new concepts easily. I was devastated as there was absolutely no warning and I am solely responsible for finances after a divorce. The RIF came immediately after I came back from attending military duty. It was also an issue with my manager whenever I was called away to complete military duties. When I was RIF'd I lost out on the opportunity to complete training for Health and Welfare which would have improved my position and wages that would have been gained by overtime. I wanted to know if I could sue the company for this loss.
