26th Cavalry, Philippine Scouts and Philippine Constabulary were high performing troops. The remaining while many showed individual courage and skill never really were very successful as units. They likely correspond to the Ukies’ territorials and recent volunteers.
The constabulary werent considered high performing troops.
They were not committed to the MLR in Bataan but to beach defense.
The Philippine Division was used mainly as a counterattack force and to hold critical sectors.
But the bulk of the MLR, and most of the counterattacking, was by the Philippine Army. They had gotten much better through the course of the campaign, unforunately as they had deteriorated physically. Being in action is good training.
