ShadowSpear isn't just military SOF, it is also LE SOF as well. With that said, the FBI's HRT is a special operations force of the FBI. You will also notice SS lists the USMS's SOG. They are special operations forces/tactical units that operate inside the United States, since laws restrict military SOF from doing so (ie Posse Comitatus). So to sum up this, they are a DOMESTIC special operations force.
How would I know what ShadowSpear is thinking? I own the website.
