What is the maximum fuel tank capacity when preparing a vehicle for loading?

When preparing a vehicle for loading in an amphibious operation, it's crucial to consider fuel tank capacity for operational readiness and safety. Three-quarters capacity is the correct choice because it strikes a balance between ensuring the vehicle has enough fuel for mission requirements while preventing potential issues associated with overloading.

Having the fuel tank at three-quarters capacity helps in maintaining optimal vehicle weight, ensuring proper buoyancy in amphibious environments, and avoiding spillage during loading and transport. If the fuel tank is filled to full capacity, the additional weight can adversely affect the vehicle's handling and maneuverability in water, and there's a risk of fuel overflow. Conversely, a lower capacity (such as one-quarter or half) might not provide sufficient fuel for the intended mission, potentially leaving the vehicle stranded or with insufficient operational range. Thus, aiming for three-quarters capacity is a strategic decision based on both operational needs and safety considerations.
