Armor OSUT | Fort Moore

Hi, my name is Kris, I’m a retired Sergeant Major in the United States Army. Over the next 10 weeks I’ll provide you with weekly updates on what your trainee is doing throughout their time in Armor One Station Unit Training (OSUT) at Fort Moore, GA.

Make sure you have your Sandboxx app installed and notifications enabled, so you won’t miss any of these important updates!

Intel Week One

Week one begins with the trainees meeting the Drill Sergeants (DS), who will be responsible for their training throughout One Station Unit Training (OSUT). This is not your traditional first impression handshake; it’s an intense time for the trainees as the Drill Sergeants receive them from the Reception Battalion and they embark upon their first challenge in the Army, the First 100 Yards.

The meaning behind the First 100 Yards dates to World War I, when Soldiers left the protection of the trench and went across the battlefield to engage the enemy. Leaving the safety of the trench meant that they had faith in their leadership and the Soldier beside them as they charged the enemy positions. In similar fashion, the new Trainees must learn to trust their new Platoon and their Drill Sergeants as they face the challenges ahead of them.

Upon arrival at the drop off point, trainees are divided into Platoons and given a brief introduction to drill and ceremonies. Once in formation, they will be introduced to their Cadre and given a history lesson on their new unit.

After their introduction, the First 100 Yards will commence. Their first task will be to conduct a resupply mission where they are required to move an arrangement of items from their start point to a designated drop off point.  This is a very stressful event where they must learn to work as a team to transport cumbersome equipment, and maintain the cohesion of their group. They will cover approximately a half mile of distance with the team moving hundreds of pounds of equipment. Once they arrive at the drop off zone, they will be required to re-assemble their equipment pallet in the same configuration it was when they found it at the start point. During this mission, they will be exposed to simulated gun fire, grenades, and artillery fire.

Upon completion of their resupply mission, each platoon will compete against each other in a series of challenges. These events include a head-to head sandbag race, medical evacuation race, and a tug of war competition.  The Drill Sergeants will be competing right alongside the trainees during these competitions and everything else they do throughout the First 100 Yards.  

Once the competition is over, everyone will gather together for a final demonstration. Simulated gunshots and smoke will fire and an Infantry squad will emerge from the woodline.  

Week One marks the beginning of the first of six phases of Armor OSUT, Yellow, Red, White, Blue, Black, and Gold. During each phase, your trainee will work to complete a set of necessary tasks and exercises in order to proceed to the next phase. Please note that there may be slight variations in each phase’s weekly schedule between companies.

During week one, Trainees are subject to total control, and every action is monitored and constantly corrected by their DS. As a result, trainees are often subjected to group corrective action, even for minor infractions. This is so that all trainees develop an acute attention to detail, and foster a sense of common responsibility among the unit.

The majority of this week will be spent in a classroom setting.  Here they will begin to learn the basic principles of the Army.  Both the Army Values and the Warrior Ethos must be memorized by the end of the first week of OSUT. Trainees can remember the Army Values – Loyalty, Duty, Respect, Selfless Service, Honor, Integrity, and Personal Courage – by using the acronym LDRSHIP. They’ll have to be a bit more creative when it comes time to learn the Warrior Ethos, which states:

I will always place the mission first.

I will never accept defeat.

I will never quit.

I will never leave a fallen comrade.

During the middle of the week, your Trainee will complete the Team Development Course (TDC). The TDC is a series of physical challenges that require the Trainees to work as a team to move themselves and pieces of equipment from one side of an obstacle to the other. These obstacles can consist of water moats, walls, and a variety of other barriers that the trainees must work together to figure out how to navigate.

Before the end of the week, your Trainee will also begin their introduction to US Mines and explosives, and they will also be issued their weapon. Your Trainee will be issued an M4 Carbine.  During their many weeks of training they will carry this weapon with them and they will be charged with the responsibility to care and maintain it while firing roughly 9,000 rounds during their training.

In your Letter to your Trainee this week, ask them how they did in the First 100 Yards and the Team Development Course, and see if they’ve made any friends in their platoon.

I’ll be back shortly with your week two update, and remember, turn on your Sandboxx app notifications so you don’t miss it!
