Corrugated Culvert Bunker Set — 6ft & 4ft Sections - 1/35

Corrugated metal culvert sections were a battlefield constant from the trenches of WWI through to the firebases of Vietnam — cheap, modular, and brutally effective as overhead cover.

This set gives you four sections in two sizes to build everything from fighting positions and personnel bunkers to drainage infrastructure and logistics revetments.

Kit contains:
2 × 6-foot sections
2 × 4-foot sections

The 6-foot sections mirror real-world military-specification corrugated steel pipe (CSP), used by combat engineers for rapid-construction bunkers, command post shells, and blast-resistant sleeping quarters.

The 4-foot sections are perfect for drainage culverts, secondary entrances, tunnel approaches, or tight fighting positions. Mixed into a diorama, the two sizes create a natural sense of scale and improvised field construction.

Historically accurate corrugation profile and surface texture. Compatible with all major 1/35 Vietnam-era US and ARVN firebase dioramas, and equally at home in WWII Pacific, Korean War, or modern FOB builds.
