The Achievement Hunters -Or Achievemen, whatever you want to call them- are actually a secret specialist group of elite Hunters whose skills rival Ozpin's and perform the most dangerous task, always achieving victory and success.

The reason the breach was such a failure was because, while Port eliminated the Adult Grimm, the Achievement Hunters entered the breach, got rid of 70% of the Grimm in 2 minutes (they took 1 minute for breakfast) and then got out of the breach long before Glynda got there, which is why no Grimm walked out of it while she was closing it.
