Abstract: Systems, methods, and apparatus include a modular tent comprising an upper tent portion having a first base surface area, wherein the upper tent portion does not include a floor surface; and a base extension that includes a floor surface having a second base surface area, the second base surface area being larger than the first base surface area, wherein the base extension is removably secured to the upper tent portion, wherein the base extension, when secured to the upper tent portion, results in a base surface area of the modular tent increasing to the second base surface area.

Abstract: Systems and methods can removably secure a set of cartridge cases on a first platform. A set of marking elements can be provided on a second platform. At least one of the first platform or the second platform can be moved to shorten a distance between the first platform and the second platform. At least a subset of the set of marking elements can thereby be enabled to mark at least a subset of the set of cartridge cases. In some cases, the first platform can be configured to removably secure the set of cartridge cases. The second platform can be configured to provide the set of marking elements. One or more moving mechanisms can be configured to facilitate moving the at least one of the first platform or the second platform.
