The deployment orders for the Stalwart Special Tactics Unit have come in. They will be doing a full force insertion, meaning that they will be bringing some spare equipment with them including the Mobile Suits and some vehicles. They will be dropping well behind the intended front lines to secure a secret military installation.
The facility is currently under Kepler's control, one of many such facilities within the heavily populated system. Sigmund also has one partially inhabited moon and a few resource bases on outlying planets within its solar system.
They aren't a powerhouse of military might, but they did have a fairly decent defense force, and they have a Space Station in orbit that is still holding out against the Narsian's anti-satellite attacks. It looks like the planet is doing better than most against this alien invasion and that the Abraham Kepler might be enough to stabilize the situation for a few days or a week until more reinforcements can arrive.
