See The World, They Said! - Rear Echelon Troops fire 1% more accurately and their rifles cool down 2% faster between shots.
I don't see any reason to discuss why this intel bulletin is weak because it's crystal clear that the effects which this intel bulletin provides are unseeable in-game. Therefore, it must be converted into something different and better like an observable bonus on the veterancy gain ratio of Rear Echelon Troops.
Have you also noted that the multiplier behind the "faster cooldown" says x 1.02 (effectively increasing the cooldown by 2% instead of decreasing). A similar thing happens with the KV1 bulletin which says "4% increased defense", while there is no string attached to it (effectively doing nothing).
Intel bulletins have been discussed quit a lot, but Relic hasnt changed them in years.
