ok 80 assault squadron, along with 77 got hammered and some tanks never reached the breach due to the LCT doors takeing hits.
remember 77 also use Borse bangalores along with otehr equipment.
ploughs were taken by 77 but failed, also so tanks like the late mr Dickensions never reached the beach but hit a mine as it came off the LTC and then he started to defuse mines.
there beaches were Sand dunes so they had differant equipment because of this.
email me and i see what i have. but D Day then and now volume 2 is a good source along with the origionl history.
