Deus Ex Mankind Divided - The Invincible Body, Fighting an Iron Devil Trophy / Achievement Guide - Block an incoming enemy explosive with the Titan Shield. [Bronze / 10G]

You can do this anytime after the third main mission (where you fix your augmentations). Combat trophies work only on enemies (not civilians or policemen). Enemies are red in Smart Vision.
I did it in a russian underground casino. You actually go there during "Side Mission 4: The Calibrator". Either do it during this side mission or return later after completing it (enemies will still be there).

You must buy the augmentation "Titan". I recommend you fully upgrade it to make this easier.
Hide behind cover and wait for enemies to throw a grenade (grenades are marked with a triangle around them). Then activate the Titan Armor and run into the grenade. This will absord the damage and unlock the trophy / achievement. You may have to shoot around to make the enemies attack you.

IMPORTANT: Make a backup save before buying the aug and going in there! You can farm all other combat trophies in the same spot. Reloading the save will also reset the augmentation and give you your praxis kits back. So you can quickly upgrade another aug for a different combat trophy.
