There is no official format for SOPs, and many units use many different formats. ATP 3-90.90, Army Tactical Standard Operating Procedures, ” (link below) provides instruction on the development of standard operating procedures (SOPs) in order to enhance efficiency and adaptability across the force. ATP 3-90.90 achieves this purpose through linking to a milWiki portal under the milSuite uniform resource locator (URL) containing guidance for tactical SOPs and unclassified examples of SOPs for reference. I hope this helps and good luck.
