The SEALS are part of SOCOM. If there is an in and out raid using helos instead of subs, then I am not the least bit surprised that SEALS are being used while a lot of Green Beanies are busy with training various new national forces...............
After Desert One in Iran (Remember the embassy hostages?) ther was a major effort focused on "Jointness" within the DOD, any officer who planned on getting more than 1 star has been required to have at least one "Purple"(other service) tour. Also with budget cuts alot of the services combined their schools, Marine MP's attend the Air Force School at Lackland, Tankers all got to the Army's armor school at Knox, and a lot of the various excersises at NTC, CAX, Red Flag, etc. include more than just one service as well. That is why we were able to pull off Desert Storm and Iraqi Freedom, the changes and updated equipment/ docterine/ training from the Reagan era refit. That included alot of Joint Training. (not the kind of joint that was popular in later and post Vietnam years either)
