If that Martian looked at battlefields, they would find that people had only muskets at the time of the Civil War and that they had repeating rifles at the time of the Spanish-American War, and then they had machine guns by the time of World War I.
Si aquest marcià mirés a camps de batalla, descobriria que la gent només tenia mosquets a l'època de la Guerra Civil i que tenia fusells de repetició a l'època de la Guerra Hispànico-Americana i que tenien ametralledores durant la Primera Guerra Mundial.
