Why is a powerful machine only as strong as its support?

Power outside the vehicle

A vehicle concentrates protection, mobility and firepower in a visible object. That visibility can hide the system that makes it useful. Fuel arrives from somewhere. Tracks wear. Crews need rest. Damaged vehicles need recovery before repair is even possible.

The result is a distinction between possessing equipment and generating combat power. The first can be counted in a depot. The second must be recreated every day.

Logistics changes tactics

Supply is not merely a constraint imposed after a plan has been designed. It shapes the plan from the beginning. Route capacity affects the size of a force. Maintenance intervals affect tempo. Recovery distance affects how much risk can be accepted.

A force with protected logistics can choose when to concentrate and when to disperse. A force with fragile logistics may have powerful vehicles but very few sustainable choices.

Resilience lives in the network

Efficient systems tend to remove spare capacity. Resilient systems preserve alternatives: another route, a repair team closer to the front, compatible parts or time reserved for maintenance.

Those alternatives appear wasteful until the primary method fails. The question is not how to remove every inefficiency. It is which redundancies protect the ability to continue acting when the system is under stress.
