Additional Tier1, 2 and 3 Prizes

So I’ve noticed that the extra prizes are given to certain groups of ranks; like 1-7, 8-10 or something like that. Now I’ve also noticed that in certain ranks there are many people in the same rank. This is more usual in the half-bottom ranks, like the hundreds or thousands. So the question is; are you going to give the price to everyone that is in that specific rank??, even though there might be hundreds of people in rank 100 let’s say…or is the prize given to the first person in that rank? or just a couple?? etc. etc.
Please let me know, as I need to decide wether I play war games or spartan ops since ranking up both is turning up really hard.

Thanks
