33rd Infantry Division: 
The Illinois Division.
When the U.S. entered WW II, the 33rd Division was allocated 
to the Illinois National Guard and was in training at Camp 
Forrest, Tennessee. After being Federalized on March 5th, 1941, 
the Division had two changes of station and participated in 
both Louisiana and Desert Training Center maneuvers before 
embarking for Hawaii in July of 1943. While in Hawaii, the 33rd 
performed guard duties at vital installations and also trained 
for jungle warfare. In May of 1944, the Division arrived in 
New Guinea and received additional training
The design and colors of the patch are reputed to have 
been adopted when one of the Regiments was in the Philippines 
to prevent the theft of Regimental property by the Moros who 
considered them taboo on religious grounds. When units were 
ordered to mark their baggage during WW I, the Regiment revived 
its old markings which were later adopted as the Division symbol. 
In addition, the black disc is said to have been used to mark 
poison gas containers in WW I, suggesting that anyone 
approaching this symbol would be in danger.
