Guidons for companies, batteries, troops, detachments and separate
platoons of the US Army's combat arms (excluding those for headquarters
units of groups and higher formations) generally follow a standard design
pattern: the field of the guidon is in the first-named branch color (e.g.
red for Cavalry) with the branch insignia, numerals and letters in the
second-named branch color.
For lettered companies of battalions of regiments, the branch insignia
is centered on the guidon with the regimental number above it, the company
letter or designation below it, and the battalion number vertically centered
between the insignia and the hoist. For lettered companies of separate
battalions, the battalion number is above the insignia and the company
letter below it. For separate companies, the company number appears below
the insignia. Named companies of battalions have an appropriate monogram
below the insignia (e.g. HH for headquarters & headquarters Troop/ Companies).
Exceptions to the above patterns are found in the infantry and the
cavalry. Infantry branch colors are light blue and white, but infantry
guidons have a national flag blue field. Cavalry guidons are horizontally
divided, scarlet over white, and they display no branch insignia. Letters
and numerals are white on the scarlet half of the guidon and scarlet on
the white half.
Unit decoration streamers are authorized for attachment to guidons
if the award is made specifically to the company. Campaign streamers are
not used with guidons. Companies that specifically qualify for a campaign
credit are recognized by the attachment of a Campaign Silver Band, engraved
with the campaign credit, to the guidon pole.
Dimensions for guidons are 20 inches at the hoist by 27 inches on
the fly with a 10-inch fork. Until recently, guidons were made of cotton
or wool bunting, but they are now being made of heavyweight rayon banner
cloth with more detailed renditions of branch insignia. Since guidons are
only replaced when they become worn out, both types may be found in service
