The question attracting the most attention right now is whether the United States will truly go all in and launch a direct assault on Kharg Island.
On the surface, the U.S. military appears to enjoy almost textbook-level advantages in joint amphibious warfare: aircraft carriers, amphibious assault ships, V-22 Ospreys, CH-53Ks, LCAC hovercraft, nuclear submarines, long-range cruise missiles, plus airborne early warning, electronic warfare, and layered air defense. Any one of these elements, taken in isolation, would be enough to intimidate most regional militaries.
The problem is that the Persian Gulf is not a neutral battlespace. Its geography, climate, hydrography, channel width, density of coastal fires, and supply distances all compress the space in which U.S. advantages can be brought to bear. Capabilities that are highly lethal in blue water or open-ocean operations may become cumbersome and reactive in the Gulf, where maneuver room is limited, supply chains are stretched, and the operational window is far narrower.
Iran, by contrast, is the side fighting from a position of prepared defense. It can rely on coastal fortifications, underground facilities on the island, short logistics lines, and pre-designated fire zones. More importantly, judging from the past several weeks of combat behavior, Iran does not look like an actor improvising under pressure. It looks more like a state that has long war-gamed typical U.S. methods of war and developed a fairly sophisticated understanding of American strengths, rhythms, vulnerabilities, and political limits.
If the United States really intends to seize Kharg Island, the most likely concept of operations would be a combination of vertical envelopment and surface assault: on the one hand, using rotorcraft such as the V-22 and CH-53K to conduct vertical insertion from the west or south; on the other, using carriers and destroyers to provide cover while LCACs race in from amphibious ships positioned roughly fifty nautical miles out, unloading M1A2 tanks, breach-and-obstacle-clearing engineering equipment, and follow-on assault forces.
