What about LeIgs as DAK or Nebelwerfers as Wehr? Hell, even a couple wehr mortars might be enough (if the damage is too low, you just spam smoke on the 17 pounder). In CoH3 there is no mortar pit to cause trouble this time
if you use LeIgs or Nebelwerfers, british can use bishop to counter , LeIgs or Nebelwerfers only kill 17pounder crew, but bishop can destory the leigs and nebel implement
