The Defense Department is trying to find vendors who can supply transportable bunkers that protect troops against blasts and shrapnel.

The Defense Department is trying to quickly find vendors who are able to ship pre-made shelters to protect troops in the Middle East as the United States’ war with Iran continues.

The department is looking for information from private contractors who can provide “prefabricated, transportable, hardened shelter systems designed to protect personnel from blast and fragmentation threats,” according to a new federal contract notice posted Monday.
