Pete, the line infantry uniform was universal for many different specialties, like the grenadier/bomber. The only real distinguishing difference would be a cloth woven flaming grenade badge in dark blue on the left arm of the bomber. An NCO's badge would be in silver thread. Bombers also carried special haversacks for the grenades. Also, as a matter of interest, the chevrons you see on the upper left sleeve are not rank insignia. They are length of service stripes. The first stripe indicates 12 months and each stripe after that was for 6 months service. Likewise, chevrons on the right sleeve were wound stripes. What rank insignia that was on the uniform by 1916 was on the lower left sleeve, being a short, red slash for corporals and a gold slash for sergeants. -- Al
Pete, I have a correction on the above info. The rank markings in the above post are for the 1914 uniform. For the Horizon Blue uniform, rank markings were as follows, all on lower sleeve:
PFC- a single dark blue stripe, at angle to cuff
Corp.- 2 blue stripes, at angle to cuff
Sgt.- a single gold stripe, at angle to cuff
Sgt. Maj.- 2 gold stripes, at angle to cuff
2nd Lt.- single gold stripe, horizontal to cuff
1st Lt.- 2 gold stripes, horizontal to cuff
Capt.- 3 gold stripes, horizontal to cuff
Major- 4 gold stripes, horizontal to cuff
Lt. Col.- 5 stripes, horizontal to cuff, alternating in color as gold, silver, gold, silver, gold
Col.- 5 gold stripes, horizontal to cuff
Generals carried the appropriate number of stars at the cuff
Sorry I gave the wrong info in the first post. -- Al
