Self explanatory. One of the very first achievement that you will get, especially if you start at the easy difficulty. No need to grind it separately, just aim for the head, keep on killing and it will pop eventually, most likely till the end of the second operation.

Pretty easy and self explanatory, very unlikely you wouldn't pop this in the course of a game, but aiming for the head is a good tip regardless.
Easier to do with rifle than pistol.

This will most likely be your first trophy. Just aim for the big heads on those Sectoids, and this trophy will unlock quick.
Merch
The head is at the top of the body, it contains the brain and vital sensory organs. The impact of a high velocity profile or a beam of super heated plasma to this area will cause grievous bodily harm, likely ending in death or permanent brain damage.
