How to unlock the Rescue Ranger achievement in Metro 2033 Redux - Definitive Guide
Once you take out the guard, the middle prisoner will stand up and thank you, unlocking the achievement. If he doesn't stand up, you may have to kill some additional soldiers upstairs and return to check again.
Then, in the Main menu, I pressed "Continue"
I started in the last checkpoint I reached, I finished the level without being spotted, and got the achievement.
Hope it can help :)
I've created a full Enlightened playthrough video, and during the Frontline mission I point out collectibles and Moral Points as well as showing where this achievement takes place and the path I prefer to take when going for Invisible Man while still gaining said collectibles and Moral Points.
You can see the full mission with all items of interest and collectibles at the 1:01:42 mark in the video.
Como chegar aos prisioneiros? Ao final do túnel da segunda ponte, existe uma entrada à esquerda (no vídeo é por onde saio) que dá acesso ao local onde os soldados são mantidos. No entanto, há um caminho secundário que é passar por baixo dessa ponte. Sua entrada fica atrás da coluna onde há dois soldados executando um traidor. Contorne a coluna, e você verá algumas madeiras e uma lamparina. A descida não será fácil, mas não há inimigos nessa área. Basta pular de local em local e seguir até o túnel. Depois, basta subir as escadas e atacar o carrasco furtivamente.
This achievement, as well as "Invisible Man" are best paired together. Throughout this mission, you will definitely want avoid confrontation with the enemies at all costs. If however, you find it necessary to dispose of an enemy guard who is in your way, be sure to knock them out rather than kill them. Killing any enemies during this mission will void the "Invisible Man" achievement. If you happen to slip up and kill an enemy, you must restart the level completely; restarting the checkpoint will not work.
As for rescuing a group of Reds from their captivity, it is highly recommended to take the path to the left from the start of the mission. Make your way past the two enemies holding a hostage and jump down to the platform below. Using the pipes here, you will eventually want to reach the bottom of this station area and make sure to put on your gas mask. Your next task will be to reach the other end of the station from down here, so traverse the rubble and make sure to disarm the four wire traps along the way. Once you reach the tunnel at the end, climb both sets of ladders and you will spot a Fascist guard taunting some Reds directly ahead. Knock him out, talk to the Reds and the "Rescue Ranger" achievement should unlock at this point. For a more detailed walkthrough, focusing on finishing the level without any kills, please use the provided video!

During the Chapter Frontline, you will come across 3 prisoners in the Nazi part of the level, in order to free them you need to kill or knockout the guard taunting them quickly before he starts executing them. This should be paired with Invisible Man. Maka91Productions has a great video for this trophy and Invisible Man in one:
