Military Sci-Fi Story for Sleep

On a dead oceanic shelf, an atmospheric processing station called the Spire has gone silent inside a spreading calcified reef. Three processor cores still regulate breathable chemistry across the shelf colonies, so a four-man salvage detail enters before the sector suffocates or is abandoned.The Bone Bunkers are not predators that chase soldiers. They grow bunkers, alcoves, medevac niches, supply mouths, and defensive walls where frightened or wounded men will take cover, then vent calming gas and turn bodies into load-bearing structure.Inside the reef, radio dies, thermal lies, motion reads nothing, and even sound is swallowed by the walls. When a tech steps into a false medevac niche and the route back begins closing cone by cone, the mission shifts from recovery to confirmed loss, with one survivor forced deeper through a place that knows exactly when men need to rest.This is "The Trojan Bunkers" by Sascha Schmidt

The White Sheet is an acid-snow permafrost plain where Tower Nine once processed atmospheric nitrogen for a human colony that stopped answering six weeks ago. Around its base, the Scissorbugs have chewed the colony into stripped alloy, resin, tunnels, and mound-work, and a breacher section is sent in to recover the signal core, plant antimatter pins, collapse the geothermal tap, and deny the nest.The team rappels onto the tower and begins the climb up the east thermal conduit. But the Scissorbugs are no larger than matchsticks, thermally invisible until too close, and the swarm’s rhythm finds the old obedience dampeners in the soldiers’ skulls, and men begin opening vents, attacking their own squad, and reaching for their own seals as if obeying an order.This is "The White Sheet" by Sascha Schmidt
