StarCraft II: Wings of Liberty/Terran units

Marine
Marines can now have shields.

Reaper
The Terran Reaper is a short ranged unit equipped two pistols and a jump pack, thereby allowing them to traverse certain types of terrain. The attacks of the reaper are much weaker than that of mechanical units like the seige tank; however this is advantageous against the Protoss immortals.

Seige Tank
The seige tank is a heavy mechanical ground unit with a long range and high damage capabilities. When in seige mode, the tank now spreads its treads in four directions while still sprouting two clamps to help keep it stationary. The seige mode attack has an area of effect, however the Protoss immortals are able to reduce its damaging effects to a minimum. While mobile and stationary, seige tanks can only attack ground units.

Tychus J. Findlay
Born on October 20th, 2468 on Mar Sara, Tychus J. Findlay is a marine who was once imprisoned and then released back into duty. The 6'7" blue eyed, grey haired, 363 lb man has a large record of criminal activity, including: theft, jailbreaking, insubordination, piracy, grand larceny and murder. After being incarcerated, his death sentance was suspended in favor of a lifetime service in the Terran Marine Corp.  Unable to change, Findlay once again was punished and sent into cryogenic confinement.  With his term of isolation coming to an end, Tychus will again return to the Marine Corp.  "Hell, it's about time."
