I recently saw a new event pass artifact that has a "Heavy Infantry Attack Speed" option, and I'm wondering if this option applies to defenders as well.
Yes, it applies to all Infantry - those you have trained in your barracks, those spawning from APCs, and any spawning from your defensive buildings. So in effect, it is an offensive and defensive artifact.
