The Outpost is often the first unit deployment structure built by players. It focuses mainly on Manpower cost for units, having the Marine and Chronite Tank available. It can later be upgraded to the Barracks for a relatively cheap cost.
The Outpost allows for the construction of Marines, the answer to Scouts, and Chronite Tanks, a powerful unit that is dangerous even into the later game.
Often the first unit deployment structure built, the Chronite Tanks offered are very effective even against other units later in the game due to having high damage shots and a big health pool.
A key unit is the Marine, which is most effective against Scouts. Although Scouts may fire faster, more marines can be constructed and wth proper micro pose a very serious threat to Forge.
