STC SRBM COB
The Standard Template Construction Short Range Ballistic Missile Concealed Operations Base is far less complicated than it's name sounds. The installation is built into an abandoned building, the side of a mountain, the rusting hulk of a ship, or anywhere that the 800 square foot structure can be put. It houses a single short range ballistic missile, and has an operating staff of 6: a commander, two communications officers, and three enlisted who cover everything from basic duty to security. The COB also has communications functions, and has access to secure line of communication. Most of the time it is a listening post with heavy strike capability.
These small COBs were built in many places around the world. They also experimented with different weapons, changing the SRBM for interceptor missile batteries, anti-aircraft missiles, and cruise missiles. These proved effective generally once, and then their location was revealed. With their missile expended and cover blown, most COBs would be deliberately destroyed by their staff who would then try to escape into native territory rather than attempt to 'Alamo' the COB.
During the end of the Resource Wars, a fair number of these COBs were abandoned by their staff, who feared being left behind in a foreign hostile country more than they feared their weapons falling into enemy hands. A few were destroyed by the deserters, but far too many were left intact. During the nameless disjointed holocaust that ended the Resource Wars, captured COBs and their weapons were used to horrifying effect. Short range nukes were used to settle local disputes, and cities were blasted down to the bedrock. Others were doused in nerve gas. Millions died, and the damage and suffering caused gave birth to the wastelands, and the Wastelanders.
Amerikka Command still makes use of this type of COB as a one shot deterrent to Federation aerospace assets. While the DMZ treaty with the Pacific Rim Coalition limits the tonnage of war material either side can deploy, the Command's pop-up pocket nuke anti-ship missiles provide a much more stringent limit. To the Command, the lose of a COB is inconsequential to the spectacle of either destroying a Federation warship, or blowing a massive hole in one.
Whiskey Tango Fort
Originally called a Mobile Infantry Pre-Fab Fort, the structure became so infamous by it's colloquial name that no one outside of jargon aficionados uses the real name. Whiskey Tango is a slang term for 'wasting time', a general response for being posted to a mobile STC like the infantry fort.
A STC WTF has an armor wall with a raised walkway, an interior courtyard with pop-up barracks, supply depot, and a large amount of open space. At each wall intersection, there is a barbette with a heavy weapon system. As the WTFort lacks a large power core, these weapons tend to be conventional firearms like rifled cannons, rather than lasers or energy weapons.
Infantry support - if the boots need to be on the ground, the WTF functions as an infantry base, allowing everything from a squad to an entire division to bivouac in place. The modular design allows for a WTF to be made to almost any size, as it is largely walls and barbettes that are linked together. Some large WTFs had walls within the walls, creating more complicated fort designs. These tended to be used more for training purposes but also ended up being used as garrison positions for suppressing local rebellions and uprisings. Given the volatile nature of the world when the first WTFs were deployed, their wrecks can be found almost anywhere.
Fire Support - a garrison of infantry and an armored wall around grouped artillery pieces or missile batteries
VTOL Support - infantry garrison protecting a helicopter depot.
MASH - infantry garrison protecting a mobile hospital.
Fortressing - an advanced form of castling, a pre-con tactical base is placed in the center of a WTF facility. As the pre-con has an integral power core, the WTF can replace conventional guns in favor of beam weaponry.
While WTFs weren't used for deploying weapons of mass destruction, the majority that were not destroyed came to host regional and ethnic forces, and became focal points of bandit kings and wasteland warlords through the Second Dark Age. Junker cities would spring up, and blow away around these forts as the occasion called for, and many of the 'caravansary' stops on the Silk Road. In many of these places the WT is long since rubble, but the spirit they engendered remains.
