The Board has remanded the Veteran's claims for service connection due to inadequate examinations and evidence. The respiratory condition claim is related to exposure during training, while the low back condition claim requires a new examination considering the in-service fall.

The Veteran's respiratory condition, including COPD, is remanded due to errors in obtaining SSA records and an inadequate TERA memo. The Board finds the AOJ erred by not attempting to obtain relevant SSA records and by relying on an incomplete TERA memo.

The Board has determined that the Veteran's claims for service connection for anxiety, depression, brittleness of teeth, chronic headaches, joint pain, and a respiratory condition are remanded due to the need for additional medical opinions.

The Board has decided to remand the cases for further development due to inadequate VA examinations and missing evidence. The Veteran's claims of service connection for sleep apnea, a respiratory condition, and bilateral hearing loss are being reviewed.

The Veteran's appeal for an increased rating for tinnitus is denied as his disability has already been rated at the maximum allowable level.,Service connection for bilateral hearing loss is denied because there is no evidence of a current hearing loss disability for VA purposes during the pendency of this appeal.,Service connection for a right shoulder disorder, headaches, TMJ dysfunction, hypertension, vertigo, and respiratory condition are all denied as there is no persuasive evidence that these conditions were incurred or aggravated by service.
