@milopax.tt: How Does the M109 Fire a 155mm Shell? 💥 The M109 uses a mechanical loading system to move a heavy 155mm projectile into the cannon, followed by its propellant charge. Once the breech is secured, the propellant generates enormous gas pressure that launches the projectile. Afterward, the breech opens and the system is ready for the next loading cycle. How impressive is this engineering? 👇 #military #engineering #technology
