I interpret breaching and tactical purposes to be inter-related, but chopping sounds like woods work or bush craft. The Jenny Wren is light weight and compact tomahawk...and I was drawn to it because of those attributes. I, however, have not breached any doors with the Jenny Wren. Although it should work in that capacity. In short, I have used it as a cutter, chopper and leverage tool in the field. However, because it is shorter and lighter...it is not as effective as a heavier axe or hatchet when used for chopping nor is it as effective for leveraging when compared to a short pry bar. In sum, I think you will find it to be a well built and versatile tool that can stand up to the challenge. I like mine because it can fill an number of rolls and it is very compact.
