H.R. No. 312 is a resolution honoring the life and legacy of Audon Sanchez Cardenas, a distinguished World War II veteran who passed away on January 31, 2025, at the age of 105. Born on July 30, 1919, in Devine, Texas, to first-generation American parents, Cardenas served in the U.S. Army during World War II, where he demonstrated remarkable bravery as a staff sergeant and squad leader.

His service earned him several commendations, including the American Defense Service Medal and the European-African-Middle Eastern Campaign Medal. After the war, he worked as a barber at Lackland Air Force Base and became certified in auto mechanics.

The resolution expresses heartfelt condolences to Cardenas's family, including his sister, children, grandchildren, and great-grandchildren, acknowledging the deep respect and admiration he garnered throughout his life. It concludes with a directive for an official copy of the resolution to be prepared for his family and states that the Texas House of Representatives will adjourn in his memory. The resolution was unanimously adopted by the House on March 6, 2025.
