The Uplifting Primer isn't, to my knowledge, in any of the existing books. It is instead an actual book you can purchase. The DM of my Geneseed group used to read excerpts out from time to time.<br/><br/>That being said, in DH, if you play a Guardsman you have three choices of "background equipment":<br/>1. Mercenary licence (for those who the IG hired on to help fill out the numbers)<br/>2. Bomb collar (for the Penal Battalion. Presumably, you're one of the lucky 1% given a dud.*)<br/>3. Uplifting Primer (for the actual Guardsmen)<br/><br/>*Penal Battalions: criminals forced into one big group. Basically, it's a convenient death sentence - you needn't waste resources on killing them yourself, AND they can dent the enemies with their own useless lives as well as soaking up enemy bullets. They each are given a gun (or maybe just a CC weapon) and the bomb-collar, and have to charge towards the enemies. At which point, once in CC-range, a button is pressed and 99% of them detonate.<br/><br/>If you're not dead yet, and one of the lucky 1%, then your new job is to run back to your own troops. If you can do this, and still survive the battle, then you are now a free wo/man. Congratulations, you earned your life back.
