If you do not have any service connected disabilities, it is worth reapplying. If you get 10% you are eligible for VA health care. Boston VAMC is excellent. I can go to any hospital in Boston but I choose VAMC. A new application requires a new hearing test, and a new affidavit with appropriate documentation. Send me a PM and I will make a list of what you need. VA claim process is very vet friendly these days. Much more likely to approve a claim.
(I went on one operation on top of APC. It was great! No slogging through shit all day long. Only had a problem once when driver went under a tree filled with millions of fire ants. Whole squad jumped off top and started ripping off all web gear and clothes. Those suckers bite! My other fond memory of tracks is they were packed with cases of c-rats. All you could eat and go back for seconds. On the ground we couldn't carry much. Thanks for the ride
