I need to write here also as there seems to be some differences in answers.
I just finished 500p speed map in which I was part of winning coalition and I did get 1st place medal, please see pics 1 & 2.
This medal was from latest 500p speed map I played.
I have other medals also which I have received from gaining coalition victory in 500p maps.
So to sum it up answer that Boris gave seems to be right and later answer here seems to be wrong, this is not really good that reps for the game give two different answers.
Please do communicate with each other what is the correct answer and give only one answer no need to confuse people.
