The US Army has an online magazine called "The Preventive Maintenance Monthly." It's also known as "PS Magazine" although I have no idea what the "S" stands for, maybe it's Service???
www.PSmagazine.Army.Mil/

PS Magazine contains articles relating to maintenance of Army equipment. I found several articles when I used "M17" and "M18" as the search's keyword.
