How to unlock the What Are You Without Your Armor? achievement in The Bureau: XCOM Declassified - Definitive Guide
The objective is to completely the shield from all body part, before delivering the final blow. Just pay attention to each limbs and make sure that they are completely black on the silhouette, then kill afterwards.
Repeat 5 times and the achievement will unlock.
If you haven't unlocked this by the end of the game....
If you have a Support in your team you can have him use Weaken. That'll take care of quite some armor.
Just make sure that every part of it is grey before killing the Muton. If there is only the slightest bit of armor left when you finish him off it won't count towards the Trophy. Simply double check before you land the final blow.
I have not yet tested it, but the Support class perk "Weaken" may assist with this. To be perfectly honest, I generally choose "Disrupt."
This one works nicely in conjunction with Don't Run, You'll Just Die Tired.
When you fight Mutons there will be a small indicator on the screen notating Head, Arms, Chest and Legs. Make sure the armored areas are removed from their entire body prior to killing. The Support Ability Weaken can assist with this task while take aimed shots at each section.
Muton's have six separate armor pieces: head, torso, both arms and both legs. (Except for the very first Muton encountered that only has a chestpiece. Killing him does not count towards the achievement.) To the right of the Muton's health bar is a diagram detailing the health of each armor piece, each piece will go from bright orange to black as it takes damage and finally destroyed. On the Muton's body the armor pieces will develop bright orange cracks as they take damage, and will disintegrate when destroyed. Liberal use of grenades and AoE abilities (mine, artillery strike, ect) will typically destroy all of the armor pieces without having to actually target them individually.
