Mars opposing your Ascendant means it is conjunct your Descendant. The assertive energy lands squarely in your relationship zone and shows up through the people closest to you.
You may not feel particularly combative yourself during this transit. Instead others bring the Mars energy. A partner becomes more assertive. A colleague challenges you directly. Someone new enters your space with an unmissable presence. The opposition works through mirrors and right now the people around you are reflecting back something about drive, anger or assertion that relates to you even though it is coming from them.
If the encounters are confrontational ask yourself what you have not been asserting on your own behalf. If they are attractive ask yourself what quality of directness or courage you are drawn to in others but not yet expressing yourself.
What you might notice: Others being unusually direct or confrontational with you. Attraction to assertive people. Relationship dynamics where someone else takes the lead. The sense of being challenged to respond rather than initiate.
