I am not sure the STATE OF THE ART on these, but maybe some of the more serious can be somehow screened to see if they need CAT SCANS (such as loss of hearing, or numbness, and tell the soldiers that they must be truthful about any symptoms...
We have cat scans in the field hospitals. Nobody involved in close contact like that would be sent back to duty without a very complete check up and scans, x rays, blood work, etc. if they were displaying symptoms like that.
