Maj. Castellano and I set forth,” said Mandrill. “Without their hard work, dedication to their profession and commitment to excellence, we would be no better than previous years. Together as a team, as Highlanders, we were perfect in achieving our recruiting missions.”Command Sgt. Maj. Jesse Castellano Jr., the outgoing command sergeant major, expressed his deepest gratitude to the leaders and Soldiers of the unit.“Recruiting can bring on many challenges, but you managed to balance your professional and personal responsibilities,” said Castellano. “It is important to me that you know that your hard work does not go unnoticed.”Mandril will be assigned to NORTHCOM in Colorado Springs, Colorado.
