Thanks astrov99!
Your post confirms all of the information I have gathered on both designators. I listed IW #1 on my current application and Intel #2. I'm a prior ET2 and have been working as a telecommunications analyst at the university where I'm completing my degree in information systems. The Intel Officer I interviewed with said that with my skill set, I am a better candidate for IW. Like H60Gunr, I would be thrilled to serve in either one.
