Which function best describes logistics in sustaining combined-arms operations during a cross-branch campaign?

• A. Providing timely, compatible resupply, maintenance, and support
• B. Coordinating with allied forces only
• C. Managing supply lines without maintenance
• D. Planning operations with no resupply

Answer: (A)

The main idea being tested is how logistics keep combined-arms operations rolling across different branches, ensuring that resupply, maintenance, and support happen when and where they’re needed, in a way that works for all services. In a cross-branch campaign, every component—infantry, armor, air, naval, and support elements—depends on a seamless sustainment network. The best choice captures that by emphasizing timely, compatible resupply and ongoing maintenance and support. This means fuel, ammunition, parts, medical care, repair capabilities, and other sustainment activities are coordinated and delivered to the right units at the right time, with systems and equipment that work across services.

Why the other thoughts don’t fit as well: one option narrows the focus to allied coordination and doesn’t address the full sustainment picture across all branches. Another option excludes maintenance, which is a critical part of keeping equipment operable and forces ready. The last option omits resupply entirely, which would stall operations and defeat the purpose of sustaining a campaign.

In short, effective logistics for a cross-branch campaign means timely, compatible resupply, maintenance, and support that keep every element of the joint force ready to execute.
