So I figured the Kit Fox is a touch too slow for typical light harass and evade tactics, but instead I am going for a Kit Fox that can aid the larger mechs at ranged. The ECM keeps the larger mechs nice and safe from LRM fire, and keeps their positions better hidden, The LRM20 and ERPPC gives it some long ranged poke so if it is staying back to protect it's friends, it can still meaningfully contribute to the fight. I went with the ERPPC over an ER Large so that I can snap a shot and not have to stay exposed for the burn time.
