A new or renewal GE membership application requires payment of an application fee for US military personnel too to have a chance to get/keep GE.
Retuning US diplomats too — military or otherwise — generally have to personally pay the GE application fee for GE membership for wanting to get/maintain GE status and thereby use GE. Otherwise it’s usually the regular lines with other US citizens at US ports of entry.

Much the same applies to many adults required to do an “interview” as part of GE renewal, possibly also related to age-related triggers to get updated photos/fingerprints. The majority of the GE renewals which I’ve seen at airports last year for my family members or others in my travel parties have involved nothing substantive more than handing over the passports, the declaration receipt/forms and doing the fingerprint+photo capture again.
