CWX (combat weather) is conventional and SOWT (Special Operations Weather) is Special Operations. The differences is in the skills training and mission support requirements. CWX support conventional units .. SOWT supports Special Operations units and teams.
To correct some that are a bit behind on their information, Special Operations Weather is NOW an entry level position, just as Pararescue and CCT are. This is a recent change.
You can get the chance to try out guaranteed in your contract. The SOWT pipeline looks like this:
Basic Training (BMTS)
Combat Control Orientation Course (CCOC) - indoc
Weather Initial Skills Training (ISC) or Weather Officer Course (WOC) (Officers require a meteorology degree or attendance at an Air Force approved course of study in operational meteorology)
Airborne School
Survival School
Water Survival School
Combat Control School (CCS - Award 3 Level in 1W0X1C) - not the same training as CCT, just at the same school.
Special Tactics Advanced Skills Training (AST)
PCA to 10 CWS at Hurlburt Field, Florida
As for schools like HALO and SCUBA, most of the SOWT guys will get HALO pretty early ... SCUBA is more specialized for them and it's treated more like Special Forces, only those that are assigned to that specific duty will get SCUBA. Things are changing in the pipeline with the new entry level option .. so this may change to where HALO and SCUBA are required for their pipeline, but as of now, this is how it is.
The SOWT guys I work with are great, spot on with their job and tactically competent. They aren't shooters, their job isn't to seek, close with and destroy the enemy .. it is to provide accurate and up to date battlefield analysis of the weather and it's impact to the mission. That doesn't mean they don't get caught in the **** sometimes, so that is why they're trained for it.
We haven't lost any SOWT guys to date.
