The Soldier is an aggressive frontliner unit for the Military Branch. Soldiers are quickly trained, and often dangerous.

Despite the title, a Soldier is an aggressive variant of the more common Jumpsuit-wearing Military units.
Soliders are trained to be reliable for consistently aggressive combat, and are often high in numbers. They rely on blasters and common weaponry, with their shared personality making them stand out in the battlefield.
The Outfit
Soldiers wear a Jumpsuit
Jumpsuits are a common across most Doomliens. Some occupations may have variation on the suit's colour or design. Some Doomliens wear entirely different outfits due to their specialized job that requires protection, or carries significance reflected on the different outfit.
Purpose
Soliders are excellent cannon-fodder units. They often advance without fear, attacking targets on sight with trigger-happy tendencies.
Good Soliders follow orders.
Soldier units often operate under the guide of General Officers on the field, or Commanders with the use of telecommunications.
Recruiting Process
Soliders are easily and quickly recruited, especially if they come with an aggressive nature. If the Doomlien in question is no fit for specialization and comes with great aggression, often times they end up a Soldier, and due to constant loss of Soldiers, there can't be turnaways.
