Flak armor
Flak armor research unlocks clothing with sewn-in metal armor to resist bullets and explosions. The source notes that this weighty armor slightly slows movement.
How it works
The project has a base cost of 1,200 research points and lists Machining and Plate armor as prerequisites. It uses a simple research bench. The description specifies resistance to bullets and explosions and describes the clothing as weighty, with a slight movement penalty. No quantified protection or speed values are provided.
