RUBOX is a field-proven (TRL 9) modular ballistic infrastructure system designed and manufactured in Poland for safe live-fire CQB, MOUT/FIBUA, and force-on-force training. The interlocking, self-supporting blocks are engineered from self-sealing ballistic rubber with a proprietary mineral infill, safely decelerating projectiles up to .50 BMG and enabling the rapid build of shoot houses, ballistic partitions, bullet traps, protective walls, and both temporary and permanent training structures—without heavy machinery. The system has been independently tested and validated to VPAM PM3 and STANAG 4569, operationally demonstrated with USMC (PM TRASYS), and is compliant with VOC and REACH declarations. RUBOX provides end-to-end capability from concept and ballistic engineering through ...
