Income from Military Disability will count as income on the means test. Benefits from the Social Security Act are exclued from said income, but military disability, as contrasted with social security disability, is not a a benefit from the Social Security Act. If your wife is 30k above median income, than you are taking the means test in any case.
I agree with Mr. Turner, your military disability pay will be counted as income in the means test along with your wife's income, and the result may be that you will not be eligible for a ch 7. You will still be eligible for a ch 13 payment plan, however, and, in most cases, my clients in similar situations to yours, have found the ch 13 plan payments tolerable, especially when compared to the debt loads they carry. All of your income, including the Social Security will be included on your Schedule I and will be compared to your expenses on Schedule J.
You must disclose all of your income from every source on your bankruptcy petition. You can, however, omit the social security income from the Means Test calculations. Income needs to be disclosed on Schedule I and on questions 1 & 2 in the SOFA. Hope this perspective helps!
