IntroductionDrill Sergeant requires that you complete the drill section in Chapter 10 without taking any damage from both the enemies and the drill itself (it's an instant kill) over the course of three waves. There has been some concern as to whether or not this achievement is glitched, but I believe I have figured out how to complete this without any chance of any said glitch occurring.
__________
General Notes- You
CANNOT skip a drill section, the over-head voice must announce the drill at 75% capability and 50% capability at different times. Meaning you must endure three waves. Don't go trigger happy on the drill, you may skip one of the stages, which will not unlock the achievement.
- It is recommended that you kill every enemy before attacking the drill. Some have reported that any enemy attacks during the final drill cutscene will void your achievement, when you are not in control of your character.
- You do
NOT need to copy your save.
- Getting hit and choosing 'checkpoint restart' will
VOID the achievement for that run, you will have to replay up to that point.
- If you do get hit, you can select 'save and quit', this will restart you at the beginning of the room.
- You
CAN do this in co-op. I would suggest it, in fact.
- If you choose to tackle this in co-op, only the host will receive the achievement, but right after it pops for you, the co-op player may choose 'save and quit' and rehost the game and invite you for their turn.
- It has occurred on occasion that you can still get hit by the drill and unlock it upon the checkpoint restart, but this isn't always the case.
Roughly 5-15 minutes into the chapter, you will be required to power a generator, which will lower the safety gates to a circular arena as well as power on a nearby bench. Use this moment to prep your inventory as you see fit (if this is your first time through, there is a circuit on the wall to your right as soon as you enter the chamber).

Weapon:My personal weapon build for this achievement is posted below, if you wish to use it:
Chaingun / Forcegun combo
Frame: Heavy Frame
Upper tool: Telemetry Spike
Upper tool tip: Diffraction Torus
Lower tool: Plasma Core
Lower tool tip: Conic Dispersal
Attachment 1: Stasis Amplifier
Attachment 2: Ammo Support
Any of the above parts can be supplemented with parts that are superior to increase damage, speed, etc (if you have the Mk-V version, by all means, use it!).
This made a relatively accurate machine gun that I could spray at enemies from a distance, while allowing me to use the secondary force gun to knock back those who were getting close. My upgrade circuits were set to give my upper tool a large damage boost (as well as reload), while my bottom tool was clip with reload. Because the gun reloads both tools at the same time, reload circuits will automatically apply to both tools on the weapon.
Aura of Heroism brought up a good tip in the comments. When you are customizing your weapon; damage, clip, reload, and rate of fire will still increase when the bar appears to be maxed out. Continue adding circuits to add traits, as there is no cap other than the circuits themselves.

InventoryAfter preparing my weapon, I found it best to heal all the way to full health, and then pack a single small health pack with me as a check for each segment of the drill segment.
My personal pack prior to this achievement:
- 1 small health pack
- 3 stasis packs (takes up one slot)
- 100 ammo clips (takes up five slots)
Again, I made sure my health was maxed prior to beginning to use my small health pack as a check to see if I had taken any damage. I brought stasis packs along in order to allow me to go stasis happy; this goes hand in hand with the stasis amplifier I placed on my weapon to help hit multiple enemies if they got in to close. The vast amount of ammo reassured that I could waste ammo without worrying about running out.
__________
PositioningYou can actually position your player to where the drill will never touch you. Upon entering the arena with the drill, there will be two stasis modules on the wall, proceed to the station on the left and stay there through the entire assault. Enemies will only approach from the two grates to the left and right sides of the drill (this is on casual difficulty, whether this is the same for other difficulties is unclear).
Enemy Spawn Vents:
You can complete this in co-op but if you choose to do so, only the host will receive the achievement; right after it pops for you, the co-op player may choose 'save and quit' and rehost the game and invite you for their turn. In co-op you can easily watch one vent apiece, making this a cakewalk, especially if both players understand what they are to do.
___________
The ExecutionOnce you are ready to go, release the safety gates and commence assault. Ignore the drill, it will cause you no problems. Watch the vents as enemies with icepicks (called Fodders/Wasters) will emerge; some of these enemies will turn into the three tentacle form (if it's the upper body half that sprouts the tentacles, they will use a ranged attack), so you may need to add some follow up shots after you have killed them. If you run into issues with reloading, it is generally okay to reload once the drill moves directly in front of you, as enemies will run directly into it's path, but be aware that one may emerge unscathed, so pay attention. After roughly eight enemies, you should have a clear shot at the drill. Take this moment to check if your health pack can be used; if you cannot use it, you clear to shoot the drill, if your health pack disappears, select 'save and quit' and give it another go. When firing at the drill, do not shoot like crazy at it. I ran into an issue where shooting it with my overpowered weapon would skip one of the waves and void the achievement. Take your time shooting the inner yellow core until it breaks, sending the drill back to it's resting state.
Before the drill returns for wave two, the announcer will say that the drill is at 75% capability. At this point be ready for more Fodders/Wasters. After completing this wave of roughly 10-15 enemies, verify that your health pack cannot be used, and carefully take out the second wave of the drill.
After it retreats yet again, the announce will state the drill at 50%, this means you are nearly there. This time around, the enemies will primarily be Feeders (quick, weak enemies). Be careful that they do not sneak through, the drill can be somewhat distracting, allowing one or two to sneak through. Use your force gun and stasis to knock them back if need be. After about 20-30 Feeders, you will have a final, clear shot at the drill.
Once the drill is destroyed, you will need to head for the door that was previously blocked. Upon opening the door, the achievement should pop. If you completely this in co-op, only the host will receive the achievement. The client in the game should select 'save and quit' from the pause menu, and host the game for their achievement.
