Hi
The 2 types of warrant officer rank on the jacket are a ww2 and a 50's .In ww2 there were 2 ranks of warrant officer, chief warrant officer which was red with a brass centre strip
running top to bottom the second rank was warrant officer which was red with brass strip running left to right. In about 1956 2 new warrant officer ranks were added and
the badge was square edged , this now gave you 1 warrant officer and 3 chief warrant officer rank which caused much confusion chief warrant officer 4 and chief warrant
officer 2 both had 2 enamel blocks with the higher grade being white metal and the lower on brass , chief warrant officer 3 and warrant officer 1 both had 2 enamel blocks
again the higher rank was on white metal and the lower on brass, the rank was changed again in 72 with new badges one for each rank , warrant officer 1 was now 1 black
square on silver, chief warrant officer 2 was now 2 black squares on silver, chief warrant officer 3 is now 3 black squares on silver metal, chief warrant officer 4 is now 4
black squares on silver .
As you have info on the ribbon I will add a bit for member not in to U.S. ribbons , first the ribbons are out of order but this happens a lot, the ribbons are listed as on the jacket, you have Army good conduct, American campaign, Asiatic-Pacific campaign with 2 campaign stars, ww2 victory medal, Occupation medal (Japan I would think), Korean service medal with 2 campaign stars, Armed forces reserve medal with hourglass device these were awarded for years of service i.e. Bronze hourglass for 10 years , silver hourglass for 20 years , gold hourglass for 30 years service, the next 2 on the rack are Philippine liberation medal with 2 campaign stars, Philippine independence medal the remaining
medals I can't help with there is the possibility that these are Philippine medal or awarded to him by his home state , the 2 on the right are Philippine Presidential unit award
and Republic of Korea Presidential unit citation.
