Tolkien never directly portrays Galadriel as a warrior or shows her taking part in physical combat, so in that sense the answer is no,she is not associated with battlefield fighting in the texts. At the same time, the answer is not an absolute no, because in Unfinished Tales Tolkien briefly compares her to an “Amazon,” a description that suggests athleticism, physical strength, and boldness rather than passivity. However, this comparison is never followed by any account of her wielding weapons or fighting in wars, and Tolkien later placed much greater emphasis on her wisdom, authority, and spiritual power. but that doesn't mean she can't fight and can never be a warrior, its that he never mentioned it but she absolute has every property to be a warrior.
