11. Several factors are probably involved in the decline initary activity. WithCommunist emphasis on the northern half of the country and the Saigon area, it is possible that the enemy's delta forces have been ordered to fill tneir needs for supplies and reinforcements from local sources only. Large numbers of enemy arms and supply caches have recently been uncovered by allied awaep operations. Despite reports of new Communist weapons and North Viotr.airasa infiltrators ir. the delta, the Viat Cong forces there are undoubtedly experiencing difficulties inully effectlvo combat-readiness posture. Furthermore, increasad allied military coordination andunder the directionew corpsmay have helped take the initiative away from the Communists.
