Soldiers, there’s a new safety of use message (SOUM) for the 120mm mortar. TACOM issued SOUM 21-008, Potential Cracks and Inclusions, on 6 Jul 21. It’s an update to SOUM 21-006, Potential Cracks and Inclusions, dated 21 Apr 21, which you can access here:
The guidance listed in TACOM SOUM 21-006 remains valid, however it instructs units with serial numbers 10000-12885 to contact TACOM for further guidance. SOUM 21-008 now specifies the maintenance interval change for the borescope and pullover found in TM 9-1000-202-14 (Feb 99, w/Ch 8, Feb 19)—which varies depending on your cannon’s serial number—for all cannon serial numbers.
