199th ODST Company

Lore
The 199th ODST Company (along with other SEAF ODST detachments) was born out of the need for a QRF that the Helldivers could use as a tactical asset. The 199th was proposed on April 4, 2186, and officially initiated on September 5, 2186. The 199th is a specialized ODST company, dubbed the "Helljumpers," because of the inherently Helldiver-esque missions. However, as a detachment of SEAF-as opposed to the Helldiver Corps-they're primary mission is supporting the Helldivers.
Playstyle
The 199th's playstyle is much more serious and finely tuned as opposed to that of the general 302nd. Weapon systems are squad distributed, and there is a much stricter catalogue of weapon systems to the 199th. This is because of the general playstyle, as well as the fact that they're SEAF, as opposed to Helldivers.
Purpose
As previously listed, the 199th serves as a QRF as opposed to a tip-of-the-spear force. They assist in aiding Helldivers who have put out SOS beacons.
