Advice on how to liquidate system

Maybe not, but I feel a "Thanks for your service" is appropriate here. Truly from my heart.

Sorry to hear about your situation. That bites. Hope it improves. Whatever you were doing with flash bangs, I suspect it was in the service of protecting others. For that, thank you for your service.

So sorry about this. Can your hearing problem be helped by increasing volume (like hearing aid)? I would be patient and give it a year before deciding anything.

Not sure if you have the same symptoms but I know someone who suffered hearing loss from blast. Doc said maybe he could’ve improved if he got some powerful steroids ASAP. He explained everything was cacophony and echo sounding, He got rid of the hearing aids and asked people to speak slowly and distinctly as yelling was minimal help and got him angry for being yelled at.

He did try wearing ear muffs for a time right after but they did not help the healing. Alternative therapies as suggested may be with a try. Herbal supplements, acupuncture, relaxation techniques.

There is also the treatment where they attach a device right to the bone in your ear. A Baha (bone anchored hearing aid) consists of three parts: a titanium implant, an external abutment, and a sound processor. The system works by enhancing natural bone transmission as a pathway for sound to travel to the inner ear, bypassing the external auditory canal and middle ear

Very sorry you have suffered this trauma

pleased to hear you seem to be receiving good medical care. Hoping you see great improvement. 
Every good wish
