I didn't gather any information if the problems or bullying within the korean army are as severe as displayed here, but I guess incidents like these will happen in any order-and-command structure with men trying to be superior of others and dealing with the power struggle. In the end drill in an army is about to give up your own willpower in subordiantion to follow what your leaders want you to do and so the shit begins to happen in one way or another.

The two ML were perfectly chosen for their part in the drama. You get the funny one, you get the more silent one, carrying their own history within life and the army along. Also the other army fellows and leaders fit very good, all acting quite flawless. A thriller and suspense story at the highest korean drama/cinematic level. It's something the Koreans are best since decades. Any minute worth to watch. You'll binge it once you start and as it's only 6 episodes...

One could argue there are some of your usual cliche bad and good guys but if it promotes the message here I can live with that. It's very interesting and diverse to get to know the different reasons and background of the deserters. Hopefully they keep the high standard in the second season as it's not often I would call out for another seasons for dramas in general.
