How many firing stays should be attached and tight on the M119A3?

The correct answer indicates that three out of the four firing stays should be attached and tightened on the M119A3. The firing stays are essential components that help stabilize the howitzer during firing, preventing excessive movement and ensuring accuracy during each shot. Each stay plays a critical role in maintaining the stability of the cannon, and having three attached allows for a good balance of security while also providing the flexibility needed for operational use.

While all four stays offer maximum stability, military practice often allows for a minimum of three to be sufficient for effective operation while still ensuring that the weapon is secure. Having a clear understanding of these components is vital for the effective and safe operation of the M119A3 in various conditions.
