I'm currently developing a world in which humanity has colonized Mars. Armed bandit attacks are common, and military enforcers are necessary to eliminate these threats.
Most combatants use firearms in this universe.
I'm aware that even a slight breach in a space suit offworld results in depressurization and death. To my understanding, even a slight graze of a bullet on a space suit will result in death. What kind of armor plate (material, thickness, and structure) would be able to effectively stop a bullet (generic intermediate powered rifle round at most, such as a 7.62x39 round out of an AK line rifle) from puncturing a suit?
Gravity is lower on Mars, so I would be fine with slightly heavier armors, but make sure a person would be able to move around properly while wearing the armor. I would like the armor to cover the same approximate areas as, say, stormtrooper armor would, to make sure that non-critical areas, if hit by a bullet, don't cause death.
