Rangers and Delta

[pmulcahy11b]

At least since the abortive raid in Iran to rescue our hostages there (IIRC 1978), Rangers have been working closely with Delta. RDF Sourcebook doesn't seen to have the two units working together; the Rangers have their own deep recon-type missions, while Delta conducts deep recon itself as well as deep penetration raids. I realize that by 2000, the age of the "great raids" is largely over, but would that sever the traditional linkage between the Rangers and Delta?
