Call of Duty 2

To get this achievement you just have to pass the training level, again pretty self explanatory.. you can do it on any skill level, but i would suggest doing it on Veteran cause the rest of the achievements in this game you have to do it on Veteran as well!

The easiest achievement in the game and also the first you'll get, all you have to do is follow the on screen instructions and complete the tutorial, there's not a great deal I can do to walk you through this as like I said, the game already does, however I've linked in a video to give you an idea of what to expect!

What the description doesn't say however is if there's a difficulty setting requirement, which there isn't, however if you feel you're up to the challenge play through on Veteran difficulty as you'll need to in order to get all of the achievements in this game.

This is the easiest achievement in the game.

The basic training is the first part of the game. It is not hard at all. I do suggest that you start the game on Veteran difficulty and finish it on Veteran difficulty on your first playthrough.

For Basic Training, you will be required to shoot a few targets and throw a grenade or two. It will introduce the basic control scheme of the game. It is like any other shooter and you shouldn't have a problem with it.

At the very beginning of the Russian campaign, you will have to complete a training course. This will teach the basics of the game. At the end, you will get this achievement.
