Does Georgia register voters by party ? How many of those voters were Republicans “voting for Biden” ?
The party of registration is a rabbit hole. Waste of time to try and make claims based on that.
It’s pretty simple to get the names of the people those military ballots in that county were issued to and ask them who they voted for. Some of them will be willing to say so under oath, either way. And that assumes that military ballots are in no way distinct from regular ballots and thus cannot be separated. If they can be separated it is even easier.
Here’s the Georgia registration form:

It doesn’t have any information about party affiliation, but it does have a box to check if you are active duty military.
The odds of 900:0 for Biden:Trump is vanishingly small.
Even if that’s all urban kids signing up to vote, Trump is still going to poll more than 35% of those voters... and in the current context, probably quite a lot more.
It does suggest that ALL the other military votes in Georgia, and everywhere else, should be looked at... because the contract for managing military voting overseas... is held by Scytl.
Georgia does not register votes by party.
