I'll say this about wings and devices for intelligence officers. They are a nice-to-have, and should not dictate or shape operations simply to get a piece of flair.
However, these wings/devices do reflect a certain degree of understanding, experience, or "been-there-too" factor that has value in the IC. They are at minimum a conversation starter, and a perception of operational experience absolutely lends credibility to intel personnel in the performance of duties, especially when seated at a table among civilians and joint personnel.
For example, at one particular 3-letter agency (which is very Army-heavy in terms of assigned personnel), naval intelligence personnel with "another" device may be able to lend more weight to discussion inputs when talking about operations. Examples could include participating in a wargame/TTX, or trying to understand what a vaguely worded RFI or PIR is really asking for. Prior-URL officers will occasionally leverage past experience as a SWO, submariner, or other community to provide operational insights to the intel process. Some 1830s coming from NSW-supporting commands may have a naval parachutist badge (and one I met had a BSM, too). With the Army element, a certain amount of "Do you have a Ranger tab, CIB/CAB, etc?" hidden stereotyping can occur, even if rarely said out loud.
