The heavy was moving back and forth trying to squish anyone who tried to disable it, and I saw two engineers standing on the hill crouched just inside the GAP radius waiting for their chance. I went closer and the idea hit me... I'll wait for him to swing his tank forward a bit and I'll ram the back to stop it from covering the flare for a few seconds. To my surprise, it worked perfectly. It was a pretty cool team effort. Just goes to show that you can do big things even with unarmed units and fire support.
