[Warhammer 40k] So I've been conscripted into the Imperial Guard. Assuming I live, how long do I have to serve, and will I ever be allowed to go home?

CONGRATULATION'S, SOLDIER!

You have survived your first battle! Let's hope it is just the first of many!

Now you are probably just *full* of questions, as most first-time, surviving conscripts are, so let me answer a few of the most regularly asked questions.

First of all, yes, we are absolutely allowed to drag you from your bed, throw you in a uniform, hand you a gun and drop you on a battlefield. The Emperor protects. 

Second, no, you will not be given shore leave. Not shooting or being shot at is your "shore leave". We know you miss your families, but the xenos scum will never stop coming and if you falter for even a second you will have no family to go home to. For the time being, your brothers in arms are your family, and the battlefield is your home.

Third, no, there is no "retirement". Does your God Emperor ever retire? Does he ever rest? Our lord is virtually dead and yet He fights the very essence of the Warp at all times. You may retire when the Emperor retires.  

Fourth, no, there is no "disability" or "veteran benefits". Who told you that? 

And finally, yes, you are being sent to fight again as you hear this. 

SO SADDLE UP, SOLDIER! WE DROP IN FIVE!
