Invasion of italy questions

[daffy2war]

Rules say supplies are fuel but all units require it. does this include inf. and art. ?
Do towed art. count as a unit crossing the strait?
Rules say bombers attack at a “4” and set-up says “8”?
thanks for the help

VI supply.  Infantry are not counted for supply consumption

Towed artillery is counted towards strait crossing

Bombers roll 8 or less
