When should vehicles be refueled according to best practices?

Refueling vehicles when they reach 1/4 tank is considered best practice for several reasons. This approach helps to ensure operational readiness, minimizes the risk of running out of fuel unexpectedly, and allows for proper planning during missions or operations. When a vehicle runs critically low on fuel, it may lead to delays or complications in logistical support or mission execution.

Additionally, keeping the fuel level above 1/4 tank prevents sediment and debris that may settle at the bottom of the fuel tank from being drawn into the fuel system. This can help maintain the efficiency and longevity of the vehicle's engine and fuel system components.

This proactive refueling strategy allows personnel to remain focused on their ground reconnaissance tasks without the added worry of fuel shortages, thus ensuring continuous operational capability.
