John - A wartime vet(meaning served during a period of wartime) is considered completely disabled at age 65 and eligible for NSC pension of a little over $1250 monthly, for a single vet. If he receives SS, it will be deducted from the roughly $1250 a month. If his SS is more than $1250 monthly, he won't receive NSC pension. If he is married, has medical expenses, and assets there are other rates and adjustments made in figuring out his rate. NSC pension is like welfare for veterans, that we earned. Here's a link to explain further.
