 The unit insignia was redesigned by replacing the squared shield with a more rounded one, eliminating the three pheons on the bend of the shield, and replacing the seven crosslets with seven blossoms of the Texas bluebonnet, alluding not only to the unit's number, but its birthplace as well.The motto "Nunquam Fractum" was replaced with "Nunquam Aerumna Nec Proelio Fractum" (never broken by hardship or battle).During its Vietnam tour the 105mm howitzers of the 1st Battalion, 7th Artillery fired more than 1,250.000 rounds in its 55 continuous months of combat while earning 11 new battle honors.
