Definitely the homing US artillery of DevM. First strike eliminates two squads, second decrews the raketenwerfer, third destroys it and fourth right on the FlakHQ.
And the Bulldozer wipes. Wow.
I'll land in Stansted Airport at about 8.15 AM and have rented a car.
If anyone needs a ride from there to Leicester there's room for 2 more people incl. standard carry-on luggage.
EDIT: I'll drive to the hotel and get some sleep before the event starts at 2pm. I don't know what hotel yet
