Welcome back! We’re going to start with a little recap because we know some of this (or all of it) is new material for much of our audience and we want to make it easier to enjoy.

We’ve talked about the Army adopting the Pentomic concept in the late 1950s. The term “Pentomic Division” was used to represent the new structure, containing five subordinate units, with the purpose of maintaining functionality across domains.

The concept was designed by Maxwell Taylor and the underlying idea was to optimize the Army’s ability to attack quickly without giving the enemy time to respond with nuclear weapons.

To accommodate this, the Pentomic Division contains different units within a single division that should reduce delays caused by communications between different commands. The first to be reorganized in this way was the @101stAASLTDIV

Yesterday we discussed CARS, the Combined Arms Regimental System, also from 1957. This was a way to maintain traditional US Army lineage, which would have otherwise been lost by the Pentomic reorganization.

In late 1960, John F. Kennedy won the presidential election, and by December the Army was looking at ways to reorganize again. Changes to Army structure were required to accommodate Kennedy’s “Flexible Response” plan.

The Army came up with Reorganization Objective Army Divisions or ROAD. This process began research and planning in 1960 and was implemented in 1965. And once again, the @101STAASLTDIV was first to reorganize.

Interestingly, Maxwell Taylor, who developed the Pentomic concept, also came up with ROAD, Pentomic’s correction, while serving as Army Chief of Staff.

In 1961, JFK was so enamored with Taylor that he pulled the retired general back to Active Duty and created a job for him as military representative to the president.

While in this job, Taylor urged JFK to push ROAD on the US Army. Then-Army Chief of Staff George Decker was also sold on the concept.

So, Taylor came up with both concepts, Pentomic and ROAD. He got both pushed on the Army. And both times, the @101stAASLTDIV was first to see the changes.

ROAD was intended to “correct” the Pentomic concept. The main weakness in the Pentomic concept was the lack of combat power – in a conventional battle with an enemy armored force, the Pentomic concept left us with too many weak spots.

ROAD divisions were intended to have the versatility and flexibility needed in order to operate in all environments, against conventional heavy forces in Europe, or against lighter conventional forces or unconventional / guerrilla threats worldwide.

These ROAD divisions were configured to function in non-nuclear environments, but COULD convert to nuclear readiness IF NECESSARY. This was the opposite of the Pentomic division, which was focused on the perceived threat of nuclear war.

This ROAD reorganization was made possible by the authorization to increase Army strength by 31,000 troops during Kennedy’s presidency, 1961-1963. The increase would bring the US Army to about 960,000 Soldiers.

Army budgets were increased during the same time period by $12-billion. All this also made it possible to form two new ROAD divisions.

In 1878, the War Department published the findings of the Hancock Board, which basically made Regiments the principal repositories of unit lineages, honors, and histories.

A company is the lowest level of command authority in the Army. It’s usually led by a Captain. Each company usually has 3 platoons, and there could be 60-200 soldiers in a company, but some might have more. We don’t need to understand that right now though.

The term “company” is usually replaced with “battery” when talking about an Artillery unit. And when it’s Cavalry, the term “troop” is usually used instead of “company”.

The next level up from a company / troop / battery is the battalion or squadron. A battalion is normally comprised of 3 companies, but can have up to 5. This could be 300 to 1000 soldiers or more.

If the company is a Cavalry unit (Armored or Air) of similar size, it is generally called a Squadron. So when we see/hear “squadron” we generally think “Cav” but understand it to be like a battalion.

The next level up from a battalion is the regiment, but the Army stopped using “regiment” as a fighting headquarters and never went back to it (with a few notable exceptions – 75th Ranger Regiment, 2nd Cavalry Regiment, etc).

Under ROAD, the battalion became the basic tactical unit, and the brigade became the principle instrument of garrison administration. This made the brigade responsible for training, recruiting, and centralized command during wartime. THIS HAS NEVER CHANGED.

One good thing about ROAD is that it allowed the Division to train as it would fight, in a Task Organized fashion. (Team Yankee does a pretty good job demonstrating Task Organization, actually. And it has tanks.) #TankTwitter

Now, we’ve mentioned Battle Groups and should probably explain that one too. Under the Pentomic division structure, the core of the Division was 5 Infantry Battle Groups, each with 5 Infantry companies, a HQ, a maintenance company, and a mortar battery.

For example, Company A, 14th Infantry was redesignated (in 1957) “Headquarters and Headquarters Company (HHC), 1st Battle Group, 14th Infantry”, and this tied the new battle group to the lineage and honors of Company A.

Instead of whole Divisions with singular functions, ROAD allowed for a force structure that could break up and fight in smaller units with all of the functions of a combined arms organization.

Our 17th Cavalry Regiment is a good example how messy the US Army regimental system can get.
