Navy Ranks on ACU jacket?

check out "R 142223Z FEB 07 Proper Wearing of BDU, DCU and ACU" Ive seen plenty of navy and airforce personnel wear the acu's in theater and they seem to all wear the proper name tapes and rank and unit patches correctly for the most part. velcro ranks can also be purchased on a variety of online military retail websites such as militaryclothing.com under name tapes section.
