After completing an estimate of the situation, you identify the enemy's most likely course of action (EMLCOA) to be: The enemy has established a strong battle position oriented south, blocking the high-speed avenue of approach. I believe that on contact, the enemy will remain and fight from this battle position. Furthermore, you identify the enemy's strength as: Well dug-in positions allowing the enemy to mass direct and indirect fires to the south along the high-speed avenue of approach from cover and concealment. Given the above analysis, which of the following is a possible enemy key weakness? A lack of indirect fires assets An inability to coordinate fires from a static position A static, fixed position with a vulnerable left flank open to attack An inability to withdraw forces to the north
