Disabling impairments and VA ratings would have no effect on Social Security benefit rates once a person reaches full retirement age (FRA). So, if your husband is now age 77 nothing that you mentioned in your question would change his Social Security benefit amount.
However, if your husband served on active duty in the military prior to 1968, he may want to double check with Social Security to make sure that deemed military wages (https://www.ssa.gov/OP_Home/handbook/handbook.09/handbook-0953.html) were considered when calculating his Social Security benefit rate.
