They made their 'allies' pay a 10% surcharge... and then spent the ammunition on a fruitless war with Iran instead. So, no, they are not sending weapons or ammunition any more.
I can't find a great reference, but Wikipedia's page is a good start. Long story short, William the Conqueror never conquered the city of London. After a lengthy seige, they came to an agreement that involved them accepting him as king in return for certain special privileges.
Its not a new idea: the City of London in the U.K. has had one MP chosen by the businesses there since the mid 13th century*. There are businesses with offices there just so they can influence the result.
** Some would say the Norman conquest. The city certainly had special privileges then, but parliament didn't exist in a recognisable form until Magna Carta.
Also the point is you would be able to book a Berlin - Romania train. Yes, with a change in Czechia, but it would be a single ticket with compensation for missed connections, much like a flight.
Seriously... Do. Not. Show. Up. Its just a bunch of adults kicking a ball around. Its not worth risking incarceration, its not even worth giving these fascists your money. Don't go. Don't watch. Don't buy merchandise. Don't engage in any way.
Sounds like a Special Military Operation.
