That sounds like a lot but really isn’t. Not for a full scale invasion. Maybe some targeted strikes but what then? If they, for example, win Kharg or any other island, what then? Either hold.it indefinirly while being droned from the mainland or give it back to Iran (and then, what’s the point?)

Holding territory is costly, you need support, food, and replacement rotating in while not really winning anything.

This all sounds like a vietnam speedrun that goes into a new afghanistan/iraq.
