US DTRA live-fire testing to improve deep-bunker strike capability

The post describes urgent, classified DTRA live-fire testing at the ALT-SHIST subterranean site at White Sands, likely aimed at validating improved capabilities for striking very deeply buried facilities (e.g., Iran’s Pickaxe Mountain bunker). While details are classified, the linkage to specialized underground test prep suggests refinement of hard-target penetration/attack methods beyond routine operations.
