TM 9–2350–311–20–2 1–4 Change 2 1–3 DESTRUCTION OF ARMY MATERIEL TO PREVENT ENEMY USE — CONTINUED When time is short, a method of destroying the equipment with materiels at hand is as follows: Retrieve or smash sighting and fire control equipment. Load cannon with projectile and full powder charge. Attach a 50 foot (15.2 m) or longer lanyard to firing mechanism. Dis- connect recoil cylinder lines and fire the weapon. Take a sledgehammer and bend the end of the counter recoil buffer rod. A second method is to close the breechblock and toss several thermite grenades down the cannon tube. Elevate the can- non tube so that the grenades will fall against the breechblock. This will melt the breech and the powder chamber, causing them to fuse together. 1–4 PREPARATION FOR STORAGE OR SHIPMENT Instructions on proper storage and shipment of the M109 self-propelled howitzer series are covered in Chapter 2, General Cab Maintenance, of this manual. 1–5 QUALITY ASSURANCE (QA) No particular quality assurance manual pertains specifically to the M109 howitzer series.
