What is the crucial requirement for the vehicle being jumped via the NATO slave receptacle?

The crucial requirement for the vehicle being jumped via the NATO slave receptacle is that it must be a 24 volts direct current system. This is because the NATO slave receptacle is specifically designed for connecting vehicles that operate on a 24-volt electrical system, which is standard for military vehicles, including the JLTV.

Using a 24-volt system ensures compatibility with modern military equipment and provides adequate power transfer for starting a disabled vehicle. This is particularly important in combat scenarios or field operations, where reliability and the ability to quickly restore vehicle functionality can make a significant difference.

While gas-powered attributes, operational status, and the ability to connect to a 12-volt system are relevant in certain contexts, they do not apply directly to the function of the NATO slave receptacle, which is exclusively meant for 24 volts direct current systems within military vehicles.
