Tech 5 was a special rank above a Corporal(2 stripes on the sleeve). The Tec 5 insignia was 2 stripes with a "T" under the stripe. Tech 4 was 3 stripes and a "T". The "T" indicates the Technical rank which meant the soldier's promotion was based on his training and the rank did not carry any leadership responsibilities. This rank was discontinued after WW2 and the "Specialists" rank was introduced.
