I had a game few days before it on escort_beta3 with a guy in BE medium tank constantly going closer to NF, getting repaired, shouting a bit and generally blocking the way to the flag. He killed about 10-20 NF and I explained him in details what has to be done. He was doing it for at least 30 minutes.

If you tell me about something else that works (gets him to front or gets him killed by NF) I'll use it.
I might also take a jeep and push such tank.
