To clarify; these examples are all of higher-end Noble Arms - Not all Arms Masters can do this and those who can do so have tradeoffs and drawbacks: An Arms Master with the power of a nuke may not have the range of one, or if they do, they may not have the endurance to sustain it for more than a few minutes. You will also be acting in coordination with larger forces - The PCs are the sharp tip of a knife, if that makes sense.
