I am with you... shorts... t-shirt or sun dress (you might look cute in one...lol) and of course flip flops.

When we are taking a snorkel tour, they are in the water with their guns. It is alittle spooky.
When we were in our late 20s, we traveled yearly to Aruba with another couple. We 2 girls would make sure we were on the beach early in the morning to watch the Dutch marines on their morning run up to where the Ritz is now and back past us; not in full gear, simply shorts...
here is a pretty interesting video of the dutch marines "landing on eagle beach"
