Why is Preventive maintenance checks and services important?

• A. It increases fuel consumption.
• B. Doing PMCS checks every time reduces injuries and improves combat effectiveness.
• C. It is optional in training.
• D. It reduces maintenance costs by ignoring minor issues.

Answer: (B)

Preventive maintenance checks and services focus on safety, reliability, and readiness by inspecting equipment before each use and addressing any obvious issues. When you perform PMCS every time, you catch problems early, which reduces the chance of injuries from equipment failure and ensures the system will perform when needed, boosting overall combat effectiveness. It’s not about increasing fuel consumption; PMCS is about preventing failures and unsafe conditions. It isn’t optional in training—it's a required practice to build safe operation and mission readiness. And ignoring minor issues to save costs leads to bigger, more expensive repairs and greater safety risks, not true savings.
