What procedure must all weapons undergo before and during deployment?

Before and during deployment, all weapons must undergo a thorough safety check and maintenance. This procedure is critical to ensure that the weapons are in proper working order and are safe to use. Such checks help to identify any potential issues that could arise during operation, including mechanical failures or unsafe conditions. The maintenance may include cleaning, lubrication, and inspection of key components to ensure reliability and functionality in a combat environment.

A thorough safety check includes confirming that all safety mechanisms are functioning correctly, that the weapon is free of obstructions, and that any necessary repairs have been made. This proactive approach is important as it directly impacts the safety of the soldiers using the weapons and the overall effectiveness of the operation. Regular maintenance and checks contribute to the weapon's longevity and operational readiness.

While other options such as routine cleaning or visual inspections by commanding officers are important in their own right, they do not encompass the comprehensive nature of the necessary safety checks and maintenance. Similarly, certification of use by the manufacturer, while relevant at the time of purchase, does not address the ongoing needs of weapon care and safety as the weapon is deployed.
