Zf726. The 38th Division has this plaque at this Battle of the Layac Junction First Line of Defense Monument site. That is an historic unit who made history in liberating Zambales and Bataan, It captured the very hard nuts to crack, the islands of Fraile, the concrete Battle Ship, Caballo Island, the sister island of Corregidor. It wiped out the Japanese (2000+ dug in with tanks and 120mm mortars over Olongapo) in very bloody and difficult fighting in the Battle of the Zig-Zag Pass.
