You can't bomb sea roads as you can't bomb land roads. Only bridges (which you can't find on EA sea roads).I think blockading is a legitimate and effective tactic - but not sure if parking one unit on a sea road is sufficient. By this logic what about bombing the sea road to cut it off - is that not the same thing as parking a naval unit on it? Would this not be a blockade by the air, attacking supply ships with air units? And we have outlawed bombing sea roads, so... When I think of a blockade, I think of a whole fleet of ships blocking a coast line.
