My current concise summary of Mars in Aries (always subject to change) reads:
Strong-willed, independent, confident. Firm in their own opinions, don't back down. Accomplishing, industrious. Knack for business, promotion, making things move. (Building & expanding organizations or industries.) Imperial (bossy?). Some have too much energy pumping through their bodies for their comfort & health.
