The day before was a long one. Your squad had been out on late evening training in the forests to the West and had gotten back to base well after dark. A quick meal was provided then straight to bed at lights-out.
You had been sleeping well until you feel the entire base suddenly shudder and hear a loud booming noise. You might normally panic but they often run drills in the scorpion at night and some of it's ammo can be really loud if it hits nearby.You roll over slightly and try to return to sleep when you hear several more loud booms and the base sirens go off. A loud undulating wailing assaults your ears before it settles down to a steady volume. Red emergency lights kick in above you bed as the base speaker system crackles to life.
"Evacuate the base. This is not a Drill. Evacuate the base." blurts out before they go silent again.
Your training kicks in and you follow the procedure ingrained in you from all of your drills. 'Dress, regroup, move-out'. You leap out of your bed and quickly grab your uniform from the locker and pull it on, shoving your smallest valuables into the pockets. You keep feeling and hearing explosions and vibrations in the floor. Some seem close while others are faint. You think you hear an AR blasting out a violent staccato against the backdrop of the constant sirens wail but you can't be sure.
Your cloak reads 3.02am. You slip your key-card over your head and check your cubicle, nothing left you can carry. You hit the door release button and step into the central corridor of Dorm A. you look up and down the corridor to try and assess the situation. The other members of your 8 man squad are spilling out of their own cubicles. There is no movement at the 10 rooms on the Western end of the dorm, nearest the courtyard. There is a second squad in dorm A with you but there is no sign of them now. Glancing to the East of the Dorm, you see the small communal area and computer station empty along with the corridors connecting to Dorm B and the gym. The doors to the central courtyard, dorm B and the Gym are all shut.
You know there are several evacuation and extraction points around the base. 'Alpha' is to the North-West in a clearing. 'Bravo' is North East in a flat section of the Rocky training area. 'Charlie' is the Dock in the lake to the South East and Delta is an area of grassland just South of the Western Forest. You also know that in the last three months, increasing numbers of small colonies have been totally wiped out by the 'Covenant' a newly discovered alien race who you have only been taught limited details of.
