I am sorry to hear about your sister's medical condition. Unfortunately, I cannot comment about military benefits because I know nothing about them.
An ex-spouse can collect disability benefits on her former spouse's Social Security record, but only if he is disabled and also collecting benefits. See here for more details: https://www.ssa.gov/planners/disability/dfamily3.html
