There is always some confusion about this during service selection. The Intel community for the Navy is organized under the 18XX designator series. Intel billets are technically "Restricted Line-Special Duty".
For NROTC, the service selection is geared HEAVILY toward URL billets. There are times when a person has a medical issue which makes them DQ for URL spots but the Intel community may want to take them depending on degree field and their grades.
If a Midshipmen really wants Intel, I would recommend asking for SWO-IP. They get their SWO pin in about 18 months, then head off and take IP courses and jump over to the 18XX community.
This is for NROTC only. USNA has a broader range of options but I will defer to the many wiser people on the forums who have the academy background and expertise.
