By sucking up the billets, I mean that we send more pilots to those stations than any other stations because they have so many aircraft and they usually transfer pilots every three years so higher turn over rate with more pilots equals greater chance of going there. One station does mulitple missions making it a heavy workload. They do the normal stuff other units do such as Search and Rescue and maritime patrols but they also guard the capitol region doing air intercepts. Lots of time away from home and the workload is immense. The other, HITRON, deploys more than just about anybody but they do no search and rescue it is only counter drug so people don't like to go there either. Neither are bad missions but some really want SAR missions because that is why they joined and others don't like the intercept mission.
Because of that, most people don't put those locations on their dreamsheets but the billets need to be filled somehow so the locations are like black holes sucking in unsuspecting victims to fill the empty billets.
