I am Dr. Moran Sciamama-Saghiv, ex-Army officer and an expert of many years on screening processes (especially yet not limited to military with an emphasis on special forces; physical aspects). I offer consultation services and a variety of lectures related to the Israeli military. I would be happy to collaborate with you (if and when relevant). In the meanwhile, I invite you to read my blog post series on the screening processes for military, law enforcement, rescue units, first responders, etc.
The United States Army, renowned for its commitment to service, discipline, and leadership, stands as one of the world's most respected military organizations.
