Now these are Reunification War/Age of War Developments. The Concepts are there just need to work on the stats which will be uploaded to this OP as soon as their done. Dunno if they should be house or Periphery Developments yet.
Comperssion Laser: a Primitive Precursor to the modern Pulse Laser Family, they generate the more heat and the same damage for 100% longer range and 50% more accuracy. Being Able to hit and reach targets that are further away than SLDF Grade Pulse lasers and being compariable in range and accuracy almost in comparison to clan Pulse Lasers. However they tend to generate more heat overall but this is a minor drawback as their tonnage is comparable to 0.5 to 2 tons more than a modern pulse laser in tonnage and 50% more bulk.
Rail Cannon: a Primitive form of Gauss Rifle technology, this lacked the punching power of the modern counterpart but it has 50% more range for the same tonnage and similar heat. At least in comparison to it's more refined Modern counterpart.
Auto Rifle Cannons: a Primitive weapon that served as a basis for the modern ultra autocannons. These Rifles can fire twice as fast in comparison to their standard counterparts and can get Jammed when mis fired. they lack the capacity of Standard Ultra Autocannons.
