While stationed at the Presidio of San Francisco he took this portrait picture while serving with the 2nd Field Artillery.

Yeager was eventually able to obtain a commission as a Lieutenant of the Field Artillery. He was commissioned as a 1st Lieutenant on November 26th, 1916. By the time of his transfer from the Philippines to San Francisco, California Yeager had been promoted to the rank of Captain. In San Francisco he joined the 2nd Field Artillery at the Presidio of San Francisco as battery commander in September 1917.

The USMF is not an exclusive "site of collectors of original items." There is a forum for Reenacting Groups and Reproduction Gear at the following link:   https://www.usmilitariaforum.com/forums/index.php?/forum/95-reenacting-groups-repro-gear/

Examples  

Model 1910 dismounted cartridge belt with rimmed eagle snaps. First ones had rimless eagle snaps. Rimmed snaps replaced with lift-the-dot fasteners in 1917. All three types used in WW1. There should be a maker and date marking on the underside of the pocket flaps nearest the two buckle halves. Value in that condition, maybe $75.00.

Yeager was transferred to the Philippines and attained a scouts commission. He was commissioned as a 2nd Lieutenant of the Philippine Scouts on February 10th, 1914. Here are some proficiency certificates for officer garrison courses taken in the Philippines in 1915 and a picture of Yeager on his favorite horse in the Philippines.   

There are examples posted on this forum of numbers for decorations on DD-214's but those examples are extremely rare. At this point you are unlikely to find anymore information than what you already have.
