This brings the war cabinet total to eight members. The decision to enlarge the group was signed into law earlier this year, and while General Raymond won’t be officially added to the roster of America’s most senior uniformed leaders until the one-year anniversary of the formation of Space Force on Sunday, December 20, he says he has already been received by his peers.
