Some other opportunities while your Marine waits to class up:

Most Marines will report to their MOS school and wait and are usually assigned misc. duties (needs of the Corps) while they wait to class up.
Waiting is a part of training too. :) They are learning patience. They may be bored but soon learn to adapt.

There may be plenty for your Marine to do. Some MOS schools may have 'working parties' Marines can sign up for and be assigned certain duties around the base. What Marines do depends on command and can be different from school to school. My son had to wait for about three months before classing up. He kept busy with guard duty, LOTS of PTing, taking MCI classes and doing maintenance (picking up lots of leaves), etc. He could also frequent the gym more. This is one thing my son missed after classes started because there was just no time for the gym.

This wait time is a good opportunity to do the admin part of their Marine career like the MCI courses. In these times of waiting it's a good time to work on these things when training and class would not be occupying all of their time. MCI classes are online classes Marines take on various subjects. They also help in promotions too.

There is also the MCMAP (martial arts) Marines can work on too to advance their belt although this may not be offered at some schools, again a command decision.

I think all Marines need to do is ask if any classes are offered or if they can volunteer for any work duties. All this is new to new Marines and they may not think to ask.

Thank you. All info helps a lot.
Comment by 1~Keri (HCC) on September 9, 2015 at 8:47pm
Unless anyone else has more updated information, I found this on the old message board but the link no longer works.
It said 2171 is approximately 230 days. This probably doesn't include the wait time to class up. Others here can fill you in on waiting.

I don't see the address on the Ft. Lee site so you may need to get the address from your Marine. Before Marines class up they are in MAT (Marines Awaiting Training) Platoon. You may need to include this with the address.

Read through the 2171 discussions above. Although some replies may be from a few months or years ago, the information and shared experiences are timeless.

Welcome Laura and congrats to your Marine on his MCT graduation! I'm sure he is happy to be at his MOS to learn and train and able to communicate evenings and weekends too!

Here is the Ft. Lee Marine Detachment site with course descriptions and more. Electro Ordnance, 2171 is listed under Bravo Co. on the right.

My son just arrived in Fort Lee for his MOS training(2171). Does anyone know how long the course is?? Can I send letters and packages?? If so, how can I get the address??

Comment by HoosierMom92 on March 12, 2014 at 11:36pm
I found this fake moto poster by accident and immediately sent it to my son at Ft. Lee while he was in hurry up and wait.

It was hard to adjust after they have all their time mapped out like at boot and MCT, but they will adjust - some.

Thank you so much for the encouragement! I will pass this information on to my Marine, I suppose I need to learn to be patient too! :)

Welcome to training in "how to wait".  This is not uncommon at all.  It is especially hard after non-stop action at boot camp and MCT. It does provide time to bond with fellow Marines and learn about the base.  Eventually they figure out how to adapt and improvise. Some are able to volunteer for various tasks, and then there is guard duty.


Comment by 1~Keri (HCC) on March 12, 2014 at 8:11pm
You may want to read back on this discussion to see what there is to do on base when the time is allowed. This seems common for Marines waiting to class up at Ft. Lee.

Learning and practicing patience is a skill too. My thoughts and prayers for your Marine and the others to learn how to adapt.

Best of luck to your Marine through this time. Hang in there, it does get better. :)
