The Tauri forces
The Stargate Command is the newest force in the galaxy. They now started the space travelling, but
thanks to their allies, they well known in the entire Milky Way. Their weapons are not very advanced, but very powerful and they are only few, but very well trained. The Earth will be the most powerful empire one day like the Ancients was, but now they are only one of the many promising civilization.
Their way to the stars was originally a secret military program, the Stargate program lead by the United States Air Force, which expanded later to international level later. Their main ground forces are the numbered Stargate teams, or SG teams. The most important and legendary is the Sg1, but there are many other teams too.
Their vehicles most important feature is the high mobility at the expense of the protection. Their main attack vehicle, the M.A.T. is a very fast assault vehicle, and its unmanned version is the U.M.A.T.
They have a few unique artillery and heavy machineguns too. The M2hb machinegun is very powerful in defence operations, the mobile M1A1 railgun is able to destroy everything with a few shots.
