Disaster Mitigation through Military Service Act

This bill amends the definition of "humanitarian and civic assistance" under military law to explicitly include "the hardening of existing infrastructure in support of disaster mitigation." It directly affects military units conducting civic assistance projects and communities receiving infrastructure upgrades. The key provision expands existing programs to allow military personnel to strengthen buildings and systems (like flood barriers or earthquake-resistant structures) as part of disaster prevention efforts. This change modifies how military humanitarian work is defined but does not create new programs or funding.
