How to unlock the Infiltrated achievement in Call of Duty: WWII - Definitive Guide
During Mission 10 'Ambush' you need to reach the sniper perch in the enemy base without being detected. Now you can be 'Detected' meaning the red awareness bar fills all the way up, however you only have a split second to kill that enemy before the base is alerted.
Once you get out of the truck you will want to follow the paths to the Right hand side until you come to a fence which you will go under then enter the building next door. Now kill the enemy in that room and continue out it and into the next building where there will be a Captain & Two Enemies and this is where your trigger finger will need to be quick as they line up you need to take the shot and kill all 3 quickly. Continue past this room and outside and continue to hug the right side while killing the enemy past the drop then the one that enters the tent to the left. Now wait for the enemies up ahead to move on and kill the one that walks your way then run up the stairs and climb the ladder for the achievement.

As with the previous stealth-related trophies, you're armed with a silenced pistol that makes this much easier to navigate undetected. Remember also to always stay crouched so that the enemies cannot hear your footsteps as easily. After killing all enemies in the ambush, you’ll progress and need to infiltrate the Air Base. You can enter the base through either the central drain pipe or head around the path to right side and go through the gap in the fence. Take the right route around then go through the first large shelter. Kill the enemy by the door then walk through to the next shelter. They'll be a few enemies in here, you can either shoot them or evade them by sticking to the right side going behind the vehicle and crates to reach the door.
Once you exit the second shelter, kill the patrolling enemy directly outside as otherwise he’ll promptly detect you. Afterwards walk straight ahead to the tent-like shelter and kill the guard underneath before dropping down. Once you drop down, there will be another enemy that patrols by the vehicle to the left as well as one further ahead, you’ll need to kill them both. Stay to the right side and wait for the remaining guards to the left to walk off in separate directions then take out the one that approaches your side. Once killed, you can head up the stairs then up the ladder to the rooftop. If you get detected by an enemy in the base then pause the game and restart from your last checkpoint.
Stick to the right side of the base. Kill enemies with a headshot or 2-3 shots to the upper body. There is one room with 3 enemies and a base commander. You can just shoot them very quickly. It's okay if a few enemies notice you. The main thing is to kill them as quickly as possible. They simply won’t have time to warn the entire base. If the icon above their head turns red, you still have a second to kill them.
If in doubt, restart the checkpoint. The trophy opens after climbing the stairs to the sniper's nest.
