 Elements of the PAVN 304th and 308th Divisions, three separate infantry regiments of the B5 Front, two tank regiments, and at least one sapper battalion were later identified among the attacking forces.Initially then, the PAVN concentrated a numerical advantage of more than three to one over the defending ARVN 3rd Division and attacked forces which were disposed to counter the infiltration and raid tactics heretofore employed by the PAVN in the DMZ area.The tactical situation on 30 March was confused; the 3rd Division received vague and conflicting reports from fire bases at an astonishing rate.
