Intro: Not every operational environment is above ground. Amidon's subterranean training complexes extend the same ballistic concrete system used in shoot houses and ranges into below-grade tunnel and room construction, for units that need to train for underground and confined-space operations specifically.

Same Material, Different Environment

Below-grade construction introduces its own structural demands - soil load, drainage, confined ventilation - on top of the ballistic requirements. Amidon's subterranean complexes use the same ABC system as above-ground structures, engineered for the additional structural conditions that come with building below grade.

Connected, Not Isolated

A subterranean complex is typically built as connected rooms and tunnel sections rather than a single chamber, allowing training scenarios that require movement through confined, low-visibility spaces - a materially different skill set than above-ground room clearing.

Why It's Part of the Product Line

Subterranean and tunnel environments show up in a wide range of real-world operational contexts. A training facility that only replicates above-ground structures leaves that gap uncovered - which is the specific gap this product is built to close.
