Unfortunately, you can't claim numbers. But if you PM one of their upper heirarchy and explain, most squads will accomodate.
Perhaps they just were not aware of the DEATHDRAGONS. Once explained, they will likely be willing to change if it bothers you.
If they are not willing to change even when asked nicely, they are very likely under the age of 14, and their squad will be gone anyway within 2 weeks to be reformed as a Luftwaffe only squad, and then two weeks later a ground vehicle only squad, and then you will never hear from them again.
