I believe you can count the "left outs" among the bicycles; they came in with the reserve battalions/reserve brigade via LCI...
Did anyone have a specific loading list for the LCAs? I'm not picturing it. Reference to "support weapons" isn't very descriptive, as to my mind, support weapons in an infantry company were pooled in Support Company, or in the Platoon Headquarters in a 1944 infantry company. Since Support Company consisted of Anti-Tank guns and Mortars (which I don't envision them schlepping ashore on D-Day), I have no idea what this could refer to. I've not seen reference to flamethrowers in use on D-Day by Canadians, either. Bunker-busting seems to have been the task of the AVsRE and Sherman DDs, or by hand grenades and demo charges when the tanks failed to show or were ineffective (in the case of the QOR and the Winnipegs).
