"VERITech" is an acryonym of the words Variable Engineering and Robotic Integration TECHnology. It is a classification of combat mecha that indicates the mecha's ability to transform into at least 2 distinct configurations. One of the configurations is always a humanoid form called the "Battloid" mode, and the other is a vehicle of some class. Most Veritech fighters also have an intermediate configuration known as "Guardian" mode or "Gladiator" mode.
Veritechs included several different types of combat vehicles, such as aerospace fighters, hovertanks and helicopters and even motorcycles. The most notable are the Valkyries, which were commonly nicknamed "Veritechs" as they were the first such mecha to ever exist.The Veritech fighter (occasionally misspelled as Varitech[3]) is a fictional fighter aircraft can transform into combat walking machine in Robotech.[4] In the late 1990s, an official backronym was invented by Harmony Gold USA for the term "Veritech:" Variable Engineering and Robotic Integration TECHnology. The name is derived from variable fighter, the term for transforming fighters used in The Super Dimension Fortress Macross (the series from which the first part of Robotech was adapted). Veritech is sometimes abbreviated "VT," though mostly in the Jack McKinney novel adaptations.
The nomenclature for Veritech Fighters partially follows that established in the 20th century by the United States Armed Forces. "V" is added to the beginning of the fighter's designation to stand for "Variable" or "Veritech". Unlike in Macross, manufacturers are generally not mentioned.
Any vehicle that is considered or referred to as Veritech, their considered transformable machine forms it can assume. Using VF-1 Valkyrie as example: They are Fighter Mode, Guardian Mode (Half-fighter/half-mecha/Battaloid) & (Mecha) Mode.
There are non-flying veritech type mecha in Robotech universe. A canon example is the VHT-1 Spartas Veritech Hover Tank seen in Robotech's 2nd season named "Southern Cross Saga"
