ArmorSim (v0.1)

A tank round meets a stack of armour, and the only question that matters is whether the shot gets through. ArmorSim is a technical 3D terminal-ballistics sandbox built around that confrontation, replacing cinematic explosions and arbitrary damage bars with material behavior, penetration models, and visible consequences. Its tone is clinical rather than militaristic: dense rods erode, plates deform, plugs break free, and fragments carry on through the target. Anyone who has ever paused a vehicle-combat video to debate armour layout will immediately understand the appeal.

Players assemble targets in a freeform editor, choosing plate materials, thickness, angles, spacing, ceramic backing, composites, and reactive armour before selecting a penetrator or shaped-charge jet. Ammunition includes recognizable American, German, and Soviet/Russian kinetic rounds, while the material database provides armour and penetrator properties rather than vague RPG-style statistics. Fast Normal calculations make it easy to alter one variable and test again, while Advanced mode reports energy use, remaining projectile velocity, and wear across individual layers. Ultra mode takes far longer but generates axisymmetric, head-on impact deformation through a continuum simulation, letting players examine craters, holes, and failed plates in slow motion with an orbiting camera.

What separates ArmorSim from a typical military sandbox is its commitment to showing its work. Material values identify whether they come from measurements, derivations, fitted estimates, or assumptions, and unsupported data is openly marked instead of quietly invented. The simulation also acknowledges its boundaries: Ultra is not a full industrial hydrocode, and its visual damage model is limited to scenarios it can responsibly handle, while the central ballistic calculation remains consistent between modes. Shareable replay files and multilingual support make it a useful rabbit hole for communities comparing results. It is less approachable than World of Tanks and far less game-like than War Thunder, but armour enthusiasts, military-history researchers, and curious tinkerers will find an unusually transparent tool for testing “what if” scenarios.
