However much you may spend your time out in the black, sometimes you need to go planetside and once there you may want to get around. If your purposes are military in nature, or you have a need to protect yourself, this book ought to be of use. It contains a detailed vehicle development system and a selection of pre-made vehicles from which you can choose whatever best suits your purposes.
The vehicle design system takes you step-by-step through the process. All vehicles in this book have been designed using this system, and it is suggested that if you want to use vehicles from the core rulebook you find the versions in here and use them instead. It's identical to the design process presented in Supplement 5: Civilian Vehicles but with a greater emphasis on things like armour and weapons, naturally, and with the numerous examples referring to military vehicles rather than civilian ones. Choices will be limited by Tech Level and by the intended function of the vehicle that you are designing.
If you'd rather pick a pre-made design, there are plenty to choose from, neatly organised into various categories: aircraft, grav vehicles, hybrids (which can operate in more than one terrain type, e.g. amphibious vehicles that can travel on land or in water), land vehicles, walkers, and watercraft. Grav vehicles are available from TL8, most of the others are available from TL1 through TL9-10... at higher levels most people use grav technology wherever they are trying to go. Each vehicle is presented with a brief description, a full set of statistics and in most cases an illustration as well. Naturally, these are fairly generic examples: if you like to use manufacturer names and models in your descriptions you will need to come up with those for yourself.
As you'd expect, these are all vehicles designed for combat - even the motorbike example has machine guns the rider can fire - and so might be of particular interest to mercenary groups equipping themselves for planetside tickets, or to those working out what vehicles may be used by the armed forces (and perhaps law enforcement) on a given planet. Like Supplement 5: Civilian Vehicles it's useful both if the party needs a particular mode of transportation or if you like to put real detail into the vehicles that they encounter during their travels. Sometimes a leather personnel carrier (i.e. your boot) is not enough, with this book you can ride in style to give battle.
