To amend the Defense Base Act to exclude Guam.

This bill amends the Defense Base Act to specifically exclude Guam from its coverage. It changes the law's definition so that Guam is no longer considered a "Territory or possession outside the continental United States" under the Act. As a result, workers in Guam who might have been covered by the Act for defense-related injuries will no longer fall under its provisions. The key change is a definitional update in the statute, directly affecting Guam's legal status under this specific federal workers' compensation law.
