Not at all true anymore. Many Guard units have been activated and deployed in the current conflict.

The old theory (Cold War) was that the Active duty would go first, then Reserve and Guard units would be ramped up if the conflict lasted long enough.

The new practice is that mainly quick response units are active duty (82nd Ariborne, 10th Mountain, etc.). Other units are in Reserve and Guard until there is a major conflict, at which time they may be among the first to deploy. Some support units are 100% Reserve and Guard, as they're not needed unless there is a major conflict.
