There is some very,very good sources on twitter.
I dont have an account,but you can look.
I get a lot from Ukraine itself,my cousin defends Avdiivka,Donetsk Region..alongside 1000s more gladiators,has done since 2015.
He got to know plenty from 72nd mech brigade as he fought along side them at Avdiivka.
So,yeah,i get bits, a bit like Tolmies Hairdoo in the tranfer stuff.
Like transfers though,shit changes on a daily/ hourly basis.
I can post 1 minute,and 2 mins later,its all changed.
Slava Ukraini.
