What type of check is performed to ensure the 5 points of contact are secure?

The type of check performed to ensure the 5 points of contact are secure is a physical check. This involves a hands-on inspection to verify that all components are tightly secured and functioning as intended. The physical check allows the operator or crew member to feel for any looseness or instability, which might not be evident through sight alone.

In this context, ensuring the 5 points of contact are secure is crucial for the safe operation and stability of the M777A2 Howitzer. A visual check, while helpful for spotting obvious issues, may not reveal problems that necessitate a more detailed inspection. Functional checks assess whether equipment operates correctly under normal conditions, and safety checks typically focus on overall operational readiness, including potential hazards. However, the physical check specifically addresses the security of those critical contact points directly through tactile confirmation.
