This package includes a project with project processing models that help you generate MGRS grids for any location on the planet.

It also includes some layouts as example of what you can do with the generated data.
It is required that you download and install the "Lat Lon Tools" plugin for it to work.
See project Metadata for more information.

There is a YouTube video (https://youtu.be/qlOx_E-odg8) that goes into more detail about this project.
