What is the purpose of the RPG-7 breech?

The purpose of the RPG-7 breech is to expel gases from the rocket after launch. This function is critical because, upon firing, the rocket motor ignites and generates high-pressure gases that need to be vented correctly to maintain the weapon's operational efficiency and safety. Properly expelling these gases prevents unwanted back pressure within the launcher and facilitates the safe and effective operation of the weapon system.

The functionality of the breech in this context is essential for ensuring the projectile's trajectory is not adversely affected by residual gases, thereby contributing to the overall accuracy and reliability of the RPG-7 when fired. Understanding the role of the breech is vital for anyone handling or maintaining the RPG-7, as it highlights the mechanics involved in its operation and safety.
