What is tactician usb?

As an AI language model, I do not have access to the context of what you are referring to as "tactician USB." However, in general, a USB is a commonly used universal serial bus that is used for connecting devices to a computer. Flash drives or external hard drives are examples of devices that use USBs. A tactician is a person who is skilled in planning or strategy, so it is possible that a "tactician USB" could be a custom USB made for someone who is skilled in planning or strategy. Without more context, it is difficult to provide specific information about a "tactician USB."
