The UK practise is for initialisms to be capiitalised and acronyms, which are prounced rather than spelled out, to have an initial capital (when rerfering to a proper noun) but lower-cased following.
So "Nasa", but "FBI".
There's some adoption of this in US English, though typically for words which have fallen into normal use and don't identify specific organisations or entities: scuba, radar, sonar, laser.
The UK style isn't uniform in all cases, particularly where initialism are pronouced with a mix of spelled-out letters and pronounced terms. So "HIV", but "Aids" (https://www.theguardian.com/society/2020/dec/01/through-posi...). I believe much US military usage falls under this pattern, as with USAMRID or USCENTCOM. In the latter case, The Guardian chooses the entirely consistent ... "USCentcom".
