My crew of my US Navy ram; HaT Gardner Gun and Strelets Russian Crimean troops and HaT British Rocket Troops gets painted.
The tropical waters look green, even brown in some light. The US Navy ram is on patrol near the island of Guam.
The ram is heavily armed to take on enemy small craft. As a ram these ships were failures, too slow to catch the ships they were designed to ram. Add small guns and machine guns they can take on small ships for smugglers and revolutionaries.
