Guernsey will play group matches against Bulgaria, Estonia, Finland and Malta.
Ranked 37th in the world, they are the second-highest ranked team in the tournament behind Spain, who they could meet in the final.
“The team has been working hard all season,” said Brooks. “We’ve tried to design our domestic season to give the team the chance to sharpen up for this tournament.
“Spain are quite well known for the way they’re playing at the moment. They had a good series against Jersey earlier this summer.”
Guernsey also warmed up for this tournament with a series against Jersey, with their island rivals winning the three-match contest 2-1.
Jersey went on to win the second T20 World Cup qualifying tournament in Germany last month.
