Japanese troops confronting the 11th and 12th PA divisions suffered significant casualties while the 11th and 12th were holding open the line of retreat to Bataan. It is hard to believe that the two PA divisions did not also suffer similar casualties. Your list also leaves out the 1st PA Div which was better trained and was their "regular" division and remained effective pretty much to the end. Nor does your list include the 2nd PA Div which was formed from the Philippine Constabulary Regiments and which also played a large part on Bataan. There were also about 12,000 "Philippine Scouts" which comprised 80% of the US Philippine Division plus the independent 43rd Inf Regt and 26th Cavalry Regt (Horse) and one-third of the Coastal Artillery units.
I'd be mildly surprised if the bulk of the Philippine Army was issued shoes, never mind bolt action rifles.
As for Philippine Army casualty totals, if they are incorrect, I am open to more accurate data. It would not shock me if they were wrong, as there is the possibility that those doing the counting (according to Wiki, the American Battlefield Memorials Commission of the U.S. Federal Government) simply didn't give a shit.
If they are correct, they certainly paint a picture. One of Fighting Filipino disintegration on first contact with the regulars of the Imperial Japanese Army.
His list might be consisting of all the divisions that were under the command of only the Philippine Army. While all the other noteworthy PA divisions and Philippine Scouts seem to the units that were more or less under the command of the US. This separation is made in the wiki on the campaign, down in the section called "USAFFE order of battle, December 3rd; causality report".
Everything was under command of the USAFFE. There was no separate PA command.
