It hasnt been clarified here so I will amplify - there are at least four different types of Int cap badges (1980-2005 era):
a) All metal/enamel: as already mentioned, was supposed to be for the forage cap, although many used it for the beret as well.
b) Cloth w/ metal star: If I remember correctly this was supposed to replace the all-metal badge. Problem is, hardly anyone ever shined the metal star, so didnt look very good when you had a cloth badge with a grey/black star...
c) All cloth: Standard issue starting in the mid 1990's if I recall correctly.
d) Field pattern: Green patch with int badge pattern for wearing on field caps.
Old pattern Intelligence Corps badge, at least two types:
a) All metal: ALL one piece silver crown and wreathe with silver scroll in middle
b) Field pattern: Green patch with Int Corps badge pattern for field caps.
