Amid an emergency blood shortage, the Armed Services Blood Program, Red Cross and the South Texas Blood Program are running Sept.19 blood drive to support the Brooke Army Medical Center (BAMC) blood supply. The Fort Sam Houston blood drive follows a 25% drop in the Red Cross blood supply, according to BAMC officials.
