Territorial Claim Unit
This unit contains a large fluid router array. By establishing an alternate data route to CONCORD networks, it grants de-facto administrative control of the system it's in to its owners.
Once online, it installs defensive protocols into the local data net which cause targeting systems to consider it an invalid target. The only way to remove this structure once it is established is to seed override protocols into more than half of the stargates in a system simultaneously. This is done by using Sovereignty Blockade Units.
