This object found on Mars has typical design dynamics of a weapon. Leftovers from the great war?

Is this a Martian weapon?
Sol 703. This object found on Mars has typical design dynamics of a weapon. Leftovers from the great war?
​
Dr John Brandenburg, a plasma physicist working as a consultant at Morningstar Applied Physics LLC, says in his book,’Death on Mars’, that nuclear isotopes found on the Red Planet “resemble those from hydrogen bombs on Earth” and a “Martian civilisation apparently perished due to a planet-wide catastrophe of unknown origin”.

According to Dr Brandenburg, Earth could suffer a similar fate if we do not learn from the supposed signs of Mars end.
​
​He writes in his book: “The discovery of dead civilisation on Mars, whose end was apparently catastrophic and due to unknown causes, reinforces our understanding that the cosmos can be a dangerous place and requires a vigorous response from the human race, to reduce the probability that we will perish the same way.”
