No, you cannot scuba dive to the Titanic. The Titanic lies in 12,500 feet of ice cold Atlantic ocean and the maximum depth a human can scuba dive is between 400 to 1000 feet because of water pressure. The increasing water pressure also restricts blood flow by constricting tissue.

Features of the ocean include the continental shelf, slope, and rise. The ocean floor is called the abyssal plain. Below the ocean floor, there are a few small deeper areas called ocean trenches. Features rising up from the ocean floor include seamounts, volcanic islands and the mid-oceanic ridges and rises.

You will see a wide assortment of head gear worn by Navy SEALs. From a boonie hat to tactical baseball caps a Shemagh or black balaclavas —it’s all mission dependent.

Most don’t, and when they do it’s mainly for show (like photoshoots). But sometimes special forces use masks (like a skull mask) for intimidation. It’s much more common to see them either not wearing any mask, or just using a scarf, but all clandestine operations groups use them.

Their modus operandi is harder than regular police, so basically, most of such units must cover their faces and conceal their identity. Most of the European special police units using various types of balaclavas to cover their faces, and those balaclavas could also be seen as part of the protective gear.

Special forces are involved in a lot of classified operations and wouldn’t want their identities to be revealed to the public. The media often publishes sensitive photos with complete disregard for secrecy. Besides secrecy, masks also filter debris such as road dirt, and sand lifted into the air by wind.

When a specific mission comes up at the pointy end, the squad, platoon, or battalion level will informally approve differences from standard operating procedure or policy. This is how individual Marines come to wear skull masks. They are unofficially allowed by their officers at the battlefield level.

You now have to wear a mask virtually everywhere on military bases — including outdoors. Defense Secretary Lloyd Austin has ordered new, stricter rules for masks on military installations, requiring virtually everyone to wear a mask even if social distancing, and whether it’s indoors or outdoors.

The official Army-designed, -tested, and -refined face mask – the Combat Cloth Face Covering (CCFC) – will be provided to new Soldiers during the second quarter of FY2021.

Technically, the skull-patterned mask (or really anything other than the issued masks) aren’t authorized, per se. However, uniform rules get stretched a great deal in combat.
