A portable soldier fighting cover having a pair of adjacent relatively rigid frames attached to an underlying waterproof flexible anchorage sheet, and defining a structure resistant to bending for spanning a military trench or foxhole, and further having a load bearing sheet attached to and overlying each frame for transmitting loads to the frame resulting from the weight of protective material such as sandbags or timber placed on the cover, and also from ballistic fragments and blast overpressure from near misses, and further having a pair of elongated straps attached to each frame and extending beyond the ends of the frames for securement to the ground for transmitting loads from the frame to the ground and for supporting the cover in the event of collapse of the foxhole side walls. Curtain sheets can be attached to the straps for service as revetments.

A soldier fighting cover for placement across the sides of a military trench or foxhole dug in the ground, the cover comprising: a pair of elongated rigid frames, each of the frames comprising a pair of elongated and parallel upper members located in a first plane, a pair of elongated and parallel lower members located in a second plane below and parallel to the first plane, the lower members being located laterally outwardly of the upper members, a plurality of intermediate cross members spaced longitudinally along the length of the upper members, and having horizontal portions located substantially in the first plane and attached to the upper members, and further having integral diagonal portions extending from the upper members and connected to the lower members, respectively, and a pair of end cross members connected to the ends of the lower members; load bearing sheets engaged upon and overlying the upper members of the frame, respectively, and attached at their opposite ends to the pair of end cross members, respectively, the end extremities of each of the sheets including adjacent slits generally horizontally aligned with the upper surfaces of the intermediate cross members; a plurality of elongated substantially inextensible high strength flexible straps attached to the frames and extending through and beyond the ends of the frames for securement to the ground, the straps passing through the slits in the load bearing sheets, and passing under the intermediate cross members whereby the straps are placed in tension between the ground and the frames to support the frames upon any downward movement of the frames toward the foxhole.
