Until 2006, veterans with a permanent disability received a monthly pension, based on their percentage of disability. In 2006, that was replaced with a lump sum payment.
The difficulty is that while service related injuries are still monitored and follow ups made, lump sum payments, to a maximum in 2016, of $310,000. At first blush, that money looked good, but accepting it meant that you had no more future claims. As well, if you are in your 20s or 30s, $310,000 doesn't go far. Among other things, the money was designed to pay for special equipment, prosthetics, physio-therapy and more.
That monthly pension wasn't "money for nothing". It was to help pay for expenses that would occur for the rest of that person's life. Soldiers missing limbs, eyes, their hearing, internal body parts that were blasted away, or severe disfigurements need support until they die.
