Now Huron....you got American Warrant Officers figgered out finally....we are all of that!
W-1 equals a 2nd Lt in pay (roughly)
CW2 a 1st LT
CW3 a Capt
CW4 a Major
CW5 a LT Col
but all are junior to 2nd Lt's in rank....but Woe be the 2nd Lt that really believes that! Let him tangle with a 4 or 5....and see who comes up short on hind end.
