What must be regularly checked to ensure the readiness of tactical vehicles?

Regularly checking fluid levels is crucial for ensuring the readiness of tactical vehicles. Fluids are essential for the proper functioning of various systems within a vehicle, including the engine, transmission, brakes, and cooling systems. Insufficient or contaminated fluids can lead to mechanical failures, reduced performance, and can compromise the safety of the vehicle and its occupants. Therefore, routine checks of oil, coolant, brake fluid, and transmission fluid levels are vital components of vehicle maintenance. Keeping these fluids at the correct levels helps prevent breakdowns in the field, ensuring that the vehicle remains operational and ready for mission requirements.

While weaponry systems, radio equipment, and navigation devices are also important aspects of a tactical vehicle's readiness, fluids are the foundational elements that directly impact the vehicle's ability to run efficiently and safely. Without proper fluid management, even the most advanced equipment cannot function reliably.
