From my experience with the Modern War 24h WD event, everything works exactly the same, except it was 30 win total for the streak, and 750 individual wins. There are faction and ind. prizes, which are the ones that can be found on the globe screen. Also, there was an issue where the same units were used for both the 24h and 72h WD events, and if you happened to fall in the same tier, you would get two units, but the bonuses didn't stack.
