Complete the game on Veteran difficulty
This is the suggested difficulty for your first playthrough, it will become frustrating but when done you will feel the other difficulties so much easier. It is hard, you do not have any healthpacks and you can only suffer 2-3 shoots.
Complete the game on Hardened difficulty
Suggested to be the last difficulty, it is as hard as Veteran, but you got healthpacks around in the game and can suffer a bit more damage.
Complete the game on Regular difficulty
Do this as the second playthrough, after Veteran you really want a break and Regular will feel as if you played God mode after Veteran. There are plenty of healthpacks and you can suffer multiple shoots even from the MG42s
Complete a mission without dying or loading a checkpoint
This is not as hard as it sounds, just do it on the first mission on Regular, shoot the first soldier with the rifle and use grenades on the next 2 in the bunker, from there on - let your teams do the rest and stay ou of harms way.
Complete a mission without taking any damage
This is not as hard as it sounds, actually did that on Veteran in Escape from the Airfield, however it can be done in any mission and in any difficulty, so you should easily get it in the first mission on Regular.
Complete a mission using only a pistol and no melee attacks.
Do this on first mission on Regular, use only your Colt - you only need to take out the soldier in the start and the 2 in the bunker, after that just let the team do the job and run for the trench
Complete a mission using only melee attacks
Again you want to do this in the very first mission, use the rifle as it seems to hit harder, again take out the soldier by the tree - only place it can be a bit hard is in the bunker since there are 2 soldiers and they will also melee you, you need to go for the one sitting and then the other, do not stand still, try to run around and melee at the same time. Alternative is to lure one of the soldiers out, but you run the risk they start firing at you.
Get kills using a pistol, rifle, submachine gun, and grenade in a mission without dying
This one might seem hard, but is also manageable in the first mission, use the Colt on the soldier by the tree, grenades against the bunker, rifle against the soldier on top of the stairs and finally use the MG to shoot at the rest, this will earn you the trophy.
