ALBANY â Federal service to the United States Marine Corps, whether in a civilian capacity or in uniform, is an extraordinary privilege that few have the honor of experiencing. Itâs an honor Trent Blalock reflected on during his retirement ceremony after 31 years of service. Blalock, who served for more than three decades, retired as deputy commander, Marine Corps Maintenance Command, at Marine Corps Logistics Base-Albany. Because of COVID-19 restrictions limiting gatherings to 10 or fewer people, the retirement ceremony was a virtual event that included Blalockâs family, Col. Wilfred Rivera, commander MDMC, and Maj. Gen. Joseph Shrader, commanding general MCLB-Albany.
