Tactics 101: 003. The Decisive Point

By Rick Baillergeon and John Sutherland

Let’s do a little practice! Here’s the scenario (click all pictures for larger versions):

dp1small.jpg

You are Commander of 3-15 Infantry (a Mechanized Heavy Task Force). You are part of a Brigade that includes 1-7 Infantry and 4-2 Infantry (also Mechanized Heavy Task Forces). Your Brigade’s overall mission is to defeat enemy forces in designated objectives in order to facilitate the maneuver of 2 BDE (behind you) to their objective (OBJ 2 BDE). Your task is to seize OBJ 3-15 in order to open a high speed maneuver route for 2 BDE. Before crossing their line of departure, 2 BDE will decide to either follow your Task Force or 4-2 Infantry (depending who has the greatest success). The mission of 1-7 Infantry is to seize OBJ 1-7 in order to protect your west flank. Following is a quick mission analysis (obviously not as detailed as needed) to give you a little more knowledge of the situation.

UNDERSTAND YOURSELF

You are the BDE Main Effort (you have priority of support)
You possess 2 Bradley Companies and 1 M1 Tank Company
You have dismounted infantry (80 Soldiers)
You have 3 mine plows (one per tank platoon)
You have smoke available

UNDERSTAND THE TERRAIN

This is the desert which means high visibility. Consequently, your initial mechanized movement will be detected.
The hills in your area of operations can be crossed by tanks at the tip of the ridges.
The rough terrain favors infantry penetration.
During the day the weather is hot. This will affect the use of smoke and the physical capabilities of the dismounted infantry.

UNDERSTAND THE ENEMY

The enemy is tank heavy (principally T72s) that are inferior to your M1s.
He will utilize a combat outpost (3 BMPs) positioned forward of his main defensive belt for security.
You do not expect much dismounted infantry.
His forces are dispersed and mutually supporting.
He has not had much time to dig-in positions or obstacles.
He will tie his defense into existing terrain.

Take some time to further analyze the mission and then determine a decisive point that will enable you to seize OBJ 3-15. Remember, decide what is that key piece of terrain, or that enemy unit, or that time or event that is the key to enabling you to seize OBJ 3-15. We will give you some potential decisive points later. DON’T CHEAT AND SCROLL DOWN!

All right, now that you have done your homework – here are some potential decisive points. (No right answer!) In the first example, the Commander believed that the key to seizing OBJ 3-15 is controlling the hilltop overlooking where the enemy main defensive belt is located. Controlling that hilltop allows him to envelop the enemy from the east and not make a frontal attack.

Our second Commander believes that the key to seizing OBJ 3-15 is the destruction of the enemy’s combat outpost north of the enemy main defensive belt. The Commander feels that the destruction of this unit will take away his forward security and enable him to envelop the enemy from the west.

Our final Commander believes the key to seizing OBJ 3-15 is conducting a simultaneous attack from both flanks. He feels that timing is critical and that each flank should be attacked simultaneously. Based on his experience, he believes that if there is a gap between the attacks, he will not be successful in seizing the objective. This Commander is truly time –oriented.

Each Commander after determining his decisive point now has that systematic path to begin course of action development. The decisive point allows him to focus his planning.

Hopefully, this article has showed you how important the decisive point is in planning. If you have not utilized this technique before, it is truly an acquired art. If you are struggling with the concept, drop us a line in the forum. We are here to help (you may have heard this before, but we mean it)!

Next time, we will discuss how to develop your course of action after determining your decisive point. Our discussion will focus on main and supporting efforts and the concepts of task and purpose.

  1. Are there any hard and fast rules about determining decisive points?

    How does one determine decisive points when they are given little information on the enemy?

    Given a very casual situation (such as an outdoor paintball match with rank amateurs) would you concentrate more on the terrain oriented decisive points, enemy oriented decisive points?

  2. Corps level is tactical but bordering the operational level.
    Are DP´s valid? …Or should we use GOG concept?

    Can you show us any historical case study about DP/COG in Corps level?

  3. are thear eny key rules that:
    decisive point has to destroy,seiz or achieve by- decisive operation or shaping operations? or both?
    thanks
