Droid Engineer Archive

I have seen several posts regarding a ‘combat droid module’. As far as I can tell, there is no such thing. Now, I admit, I am not a master DE (barely above novice), but I do not have the schematics for such a device, nor can I find it listed on the skills page for a DE. I thought, maybe Weapons Smith, Armor Smith or Artisan, can not find it there either.

So, where is the ‘Combat Droid Module’ in the skill tree?
Or is this something you have to quest for?
