Military Cover up?

I have had some trouble lately with the Army and their lack of interest in and willingness to hide the incidents and reports associated with the blasts that my husband was in and near. I have been requesting the incident reports and sworn statements of the soldiers involved on the incidents that cause my husbands TBI. Well after waiting for 4 months with no reply and being ignored, I finally reached the colonel I left over 10 messages for in 1 week. Well guess what- "No such incident or IED ever happened on or around those days"! We know they did. I have sworn statements for these incidents from other soldiers journals. I finally had it with a colonel the other day and said " Funny how these men went over there for a full year 2 deployments and NOTHING happened! No IED's no trouble, no bombs, everything was peaceful and calm! I want to know what happened to my husband then." I am at the point of calling every news place in this country to unleash a full investigation as to why and where these reports are being covered up! No purple heart without them. This kind of stuff keeps soldiers from ever getting their TBI verified.
