The M18s were busy engaging the heavily fortified positions around Clark Field on January 29 when, suddenly, six Type 97 Shinhoto Chi-HA of the Japanese 10th Tank Regiment attacked from the northwest, blasting an M7 Howitzer motor carriage and inflicting heavy casualties on a company of infantry trapped in the open. There was no room for tactical maneuver. In spite of their eggshell armor, five M18s rushed to engage the Japanese tanks, trading shot for shot with them.
Attacker: Japanese (Elements I Co., 10th Tank Regiment)
Defender: American (Elements 37th Infantry Division; 637th Tank Destroyer Battalion)
