The photo also doesn't really do justice to how much stuff was going on at one time since it just makes it look like supplies are being delivered to a beach. You've got an an incredibly dense (in terms of participants per area or volume) naval battle, infantry engagements, air superiority operations, close air support and logistics operation all at the same time in roughly same place and even if you pick one aspect to focus on you'll find that the scale and tempo of operations in any one area exceeds what's "normal" even for a pitched battle.
