There are a number Afghan and Iraq War veterans that when they were involved in an attack, especially explosions, were not sent to be checked out thus making their TBIs unreported as an injury received during combat. These veterans deserve to get a purple heart just as those who are now getting examined for a TBI right after they've suffered through a blast will.
Also, PTSD has never been consider a wound of war that is placed under the 'injury' status to receive a purple heart. These veterans' long standing, if not life long injury needs to be recognized for what it is, an injury received while serving their country and thus be awarded the purple heart.
