Point defense weapons systems, or PDWs, are weapons designed to track and intercept incoming munitions or craft. They focus on putting up a wall of projectiles to deflect, damage, and destroy threats to their parent warship.

The first plasma weapons were created at the turn of the last century. These gigantic and unwieldy laboratory-bound devices would heat a gas until it became ionized, then project this plasma toward the intended target. Their more modern incarnations create a mass of impermeable plasma which is then accelerated down the barrel to three times the speed of sound by electromagnetic fields.

The URN's primary passive defensive system is the use of a multi-layered armor scheme which is designed to stop, dissipate, and or deflect an incoming attack. This is achieved through the use of standard armor plating, electric reactive armor, and the effective use of double hulls and their resulting hull cavities.

While the Umbrian Republic Navy utilizes railguns for both point defense and ship to ship engagements, they supplement these weapons with extensive missile armament on most warships. Housed in vertical launch tubes buried in the outer hull of the vessels themselves, small frontline warships may carry hundreds of these munitions, while the largest battleships are equipped with thousands.

The basic formation of the Umbrian Republic Army, the legion is a unit of ten thousand soldiers which is considered large enough to allow for independent tasking and assignment. A legion's equipment will vary based on the type of legion and its specific mission parameters. It may also be augmented with independent sub-units which provide specific support functionality.

The first thing an Archus commanding their fleet needed to consider was the features of the battlespace which he or she would fight in. Gravitational fields, surrounding astronomical features, and even space weather could all influence the outcome of a battle. Once the field of battle was chosen, the course of events generally followed a similar pattern.
