Even better than the petard is the LCT(R) that really really smashes everything up, I looked them up and found some funny stuff. I was playing the British and I saw that my unit 101 LCT(R) could sail right up to the shore and paste the germans real good. But I looked them up on the net and found this at
https://en.wikipedia.org/wiki/Unrotated_Projectile they said
The Mattress for the Land rocket was limited in elevation from +23° to +45° which restricted the minimum range to 6,700 yd (6,100 m).
Three spoilers were made, which could shorten the range in stages to 3,900 yd (3,600 m).
Maybe then these craft should not be allowed to come up to the shore and fire straight at stuff because minimum range is about 3 miles. Maybe these should be off board units.
They are unit 101 in the British Canadian India AustraliaNZ OOBs. I looked a lot but could not find that the Canadians Indians or Australians or New Zealanders used any of them
Theres lots more about them at this place
