House Concurrent Resolution No. 155 recognizes San Antonio's deep-rooted connection to the military, which has been integral to the city's culture and economy for over three centuries. The resolution highlights the historical significance of San Antonio as a military hub, beginning with the establishment of the San Antonio de Bxar Presidio in 1718 and continuing with the development of Fort Sam Houston in the early 1900s. Today, San Antonio is home to Joint Base San Antonio, the largest base in the U.S. Department of Defense, which plays a crucial role in training and support for the military, employing over 100,000 individuals and contributing significantly to the state's economy.

In recognition of its longstanding support for the military community, including active and retired service members, the resolution proposes to officially designate San Antonio as "Military City Texas." This designation acknowledges the city's efforts in securing substantial funding for military-related infrastructure and services, as well as its commitment to honoring military personnel through various events and educational resources. The resolution stipulates that this designation will remain in effect for ten years from the date of its passage by the legislature.
