The Holar Tower was later attacked by SRPA Black Ops soldiers and Sentinels on May 17th, 1953. It was a massive operation with over 75 VTOLs ferrying soldiers and dozens of F-86 Sabre jets. However, the assault underwent a Chimeran ambush, with Stalkers, Advanced Hybrids, and Steelheads totally miring both ground and air forces. Some of the remaining American forces managed to escape, but about 1,000-2,000 human personnel were killed. Ultimately, the attack was a costly failure which worsened with the deaths of distinguished Sentinel members, SPC. Aaron Hawthorne and Sgt. Benjamin Warner, being killed by Daedalus. After the mission SRPA made four more assassination attempts on Daedalus.
