It is not currently required to take the shot and yet over 40% have.
This is partially false and partially true. Firstly, the Army is made of up of 3 parts - 1) active army, 2) national reserves, 3) state reserves. If any of these branches, or parts of them, get "activated" for a mission, then they can be required to take the jab. Then, you have different rules for the different parts (state vs fed). I suspect that some of this 40% was forced, based on "orders" related to upcoming missions.

I currently know of a few people who have a deadline,
in a few days, to make a decision on either to reject it 100% and be kicked out, lose pensions, etc. Or, they are exploring legal actions. It's a horrible spot to be in.
Please pray for them.
