Why do you think some soldiers don't reenlist? Could it be toxic leadership, lack of potential, or lack of motivation?

Many questions and fewer answers,when my unit was activate to go to Iraq many soldiers in my unit did not reenlist because of the fear of being killed,hell we were a infantry company who trained for this sort of thing.I think family plays a big part of their decision not to reenlist.I reenlisted when I was on my first deployment to Iraq,I was stationed at Camp Scania 2005/2006.

There are as many reasons as there are soldiers. In very few cases is it a lack of anything other than the desire to stay in at that point in time. ROTC and West Point get a decent share of prior service personnel and I don't think they would say that it was a bad decision for those soldiers to not re-enlist.

I believe there is some merit in saying that some people refrain from reenlisting because of toxic leadership. To continue to progress to the next rank, there are things that a specialist cannot do without the consent of the leadership such as schools. In a toxic environment, schools are not handed out evenly. Additionally, in a toxic environment, soldiers are not always awarded for their accomplishments, which also hinders career progression.
I do not believe that anyone suffers from the lack of potential, everyone has it in them to reach for the stars. The lack of motivation to reach their potential is an almost chronic issue in the lower enlisted these days. Ask yourself this, when was the last time you witnessed a group of soldiers doing something that would eventually benefit them like area beautification without being forced to do it? Or, how many E-5's are you aware of that actually call their squad together after duty hours just to talk with them about other things besides work? How can they know their soldiers without that interaction?

I believe several reasons.
1.) Millennials are tech savvy, want an explanation, got have it right now, on my own without someone telling me what to do type of people. GenXr's are Do it because I told you to, tech dumb, I can wait for the right answer type of people. Both have there merits but are having a real hard time bridging the gap between the two and millennials are walking away because of instant gratification versus trying to work it out. Older leaders aren't listening to the youngers ones ideas...that leads me to toxic.
2.) There are some toxic leaders and some that are referred to as toxic leaders. The toxic leaders are the ones that are all about themselves and taking ideas from their subordinates and using them for themselves to get ahead and throwing others under the bus when accountability comes around. The ones that are referred to as toxic are the ones that are taking action and are seen as toxic to a unit when actions without explanation are taken and change occurs. Need to do away with the first and modify the seond to get rid of the toxic talk.
I do think that younger people lose their motivation quicker than older folks just because of the instant gratification electronic mode we live in. However, it is incumbent on us as leaders to figure that out and use that to the units advantage and keep this generation motivated. If we don't we will lose more and more solid good people.
Lastly, some people just leave because the military is just not for everyone. Great on those that served for a initial tour and got out...my hat is off to them because they still did more than a majority of this nation did. Sometimes opportunities are just better for them and their families and we can't fault them for that.

It varies based on the individual. In my case, I got tired of deploying and didn't trust my chain of command. I also outgrew it. I literally dreaded going to work everyday so it was time to go.

i agree with everything everyone saying here,most of my buddies here in hawaii are calling quits because they can't handle their leadership no more. Even the nco's here are calling it quits. Don't know if it's being hawaii or just they aren't ''fit'' for the army anymore

As a Specialist, I witnessed three GREAT Soldiers ETS because their Team Leader (E-5) was constantly complaining about what it was like "being an NCO." Everything he spoke about was negative and he always told them they should get out while they can. Another reason I am aware of is the false impression that money will be better in the civilian sector. This is not always the case but most Soldiers do not realize the benefits they have with the military. I am currently outlining this topic to write a book on the financial influence on first-term Soldiers. Everything boils down to money.

Maybe because they just can't cope or are not cutout for the military structure and discipline.

I think some of it is expectation. You join expecting something and then it isn't what you expected.
