I'd also factor in time of day. If we assume normal military operations, besides night practice flight operations, I think most of military would be sleeping or in morning PT right now.
I've seen Test1234 for several days now, so that one might be normal.
I just checked, and there is one plane in the entire country in flight. It's Idaho17, flying near Savannah, GA. It's a Beech C-12R+ Huron.
Until a few minutes ago, there was a transponder on the ground in Miami squawking as Test1234.
Maybe it's normal, but I'm used to seeing lots of military planes across the country. Maybe they are there, but not squawking.

Could it be weird, 100%. Who knows though.
