Mars governs drive and anger — how you pursue and how you fight. In Libra, that function takes on balance, fairness and acute awareness of other people — a Cardinal Air expression ruled by Venus.
Where it strains
Avoids decisions to avoid disappointing anyone, which disappoints everyone eventually.
Reading a placement properly
Mars in Libra describes a function in a style. It says nothing yet about where that plays out — for that you need the house, and the house needs a birth time. A placement read without its house is half a sentence.
