Mechwarrior Online - I Need To Know

Waited in the basement for the enemy push in but my team kept poking out and dying. When we were down 9, I pushed out and caught an assault mech with streaks. Well having ECM meant he could not lock on me so I crushed him with SRMs, but they had 8 other mechs, and killed me. I needed to know that I could take one of them down with me.
