Narrative:
I assumed the position of 41 radar and data controller. My briefing consisted of advising me that the la veta and chama north and south MOA's and atacc's were hot. Data blocks were started indicating that the areas were hot. The area is coordinated on a real time basis, meaning until coordinated through supervisors, the area is cold. I was briefed by a radar trnee on his last radar sector, with the OJT instrument sitting behind the radar trnee by about 4'. The radar trnee and his instrument took a break 3-4 mins later the adjacent low altitude sector controller called sector 41 with a departure off of alamosa wanting to know how to get the aircraft off with all the MOA's and atacc's hot. 5 mins later a corp jet departed cos and I had a conversation with the pilot explaining what I had to do in order to avoid the MOA's and atacc's. I took the handoff on military flight X (2 fgt's) at approximately XA40. At approximately XA45 I cleared X flight into the la veta MOA's and chama north and south atacc's. After X flight reported established within the areas I terminated their radar service and advised changing to tactical frequency was approved. At approximately XB00 the 41 radar trnee and his instrument returned to train again. At this time I briefed both that 'all the areas are still hot. I cleared 2 fgt's into the la veta/chama areas,' and other information not related to this problem. 10 mins later I received a call from the area supervisor asking if I cleared an aircraft into the la veta/chama areas. I said, 'yes, military X flight--2 fgt's.' after I returned the sector above sector 41, sector 29 found out about the areas being cold now. The problem was sector 29 was not protecting for the la veta/chama area's in the first place. 8 aircraft or so penetrated the airspace from FL240-FL290 during the time that X flight was in the area. No aircraft saw each other. The problem was the briefing I received was inadequate and misleading to the point that this situation occurred.

Title: SEVERAL ACFT CLRED THROUGH ACTIVE MOA AREA. OPERATIONAL DEVIATION.
Narrative: I ASSUMED THE POS OF 41 RADAR AND DATA CTLR. MY BRIEFING CONSISTED OF ADVISING ME THAT THE LA VETA AND CHAMA N AND S MOA'S AND ATACC'S WERE HOT. DATA BLOCKS WERE STARTED INDICATING THAT THE AREAS WERE HOT. THE AREA IS COORDINATED ON A REAL TIME BASIS, MEANING UNTIL COORDINATED THROUGH SUPVRS, THE AREA IS COLD. I WAS BRIEFED BY A RADAR TRNEE ON HIS LAST RADAR SECTOR, WITH THE OJT INSTR SITTING BEHIND THE RADAR TRNEE BY ABOUT 4'. THE RADAR TRNEE AND HIS INSTR TOOK A BREAK 3-4 MINS LATER THE ADJACENT LOW ALT SECTOR CTLR CALLED SECTOR 41 WITH A DEP OFF OF ALAMOSA WANTING TO KNOW HOW TO GET THE ACFT OFF WITH ALL THE MOA'S AND ATACC'S HOT. 5 MINS LATER A CORP JET DEPARTED COS AND I HAD A CONVERSATION WITH THE PLT EXPLAINING WHAT I HAD TO DO IN ORDER TO AVOID THE MOA'S AND ATACC'S. I TOOK THE HDOF ON MIL FLT X (2 FGT'S) AT APPROX XA40. AT APPROX XA45 I CLRED X FLT INTO THE LA VETA MOA'S AND CHAMA N AND S ATACC'S. AFTER X FLT RPTED ESTABLISHED WITHIN THE AREAS I TERMINATED THEIR RADAR SVC AND ADVISED CHANGING TO TACTICAL FREQ WAS APPROVED. AT APPROX XB00 THE 41 RADAR TRNEE AND HIS INSTR RETURNED TO TRAIN AGAIN. AT THIS TIME I BRIEFED BOTH THAT 'ALL THE AREAS ARE STILL HOT. I CLRED 2 FGT'S INTO THE LA VETA/CHAMA AREAS,' AND OTHER INFO NOT RELATED TO THIS PROB. 10 MINS LATER I RECEIVED A CALL FROM THE AREA SUPVR ASKING IF I CLRED AN ACFT INTO THE LA VETA/CHAMA AREAS. I SAID, 'YES, MIL X FLT--2 FGT'S.' AFTER I RETURNED THE SECTOR ABOVE SECTOR 41, SECTOR 29 FOUND OUT ABOUT THE AREAS BEING COLD NOW. THE PROB WAS SECTOR 29 WAS NOT PROTECTING FOR THE LA VETA/CHAMA AREA'S IN THE FIRST PLACE. 8 ACFT OR SO PENETRATED THE AIRSPACE FROM FL240-FL290 DURING THE TIME THAT X FLT WAS IN THE AREA. NO ACFT SAW EACH OTHER. THE PROB WAS THE BRIEFING I RECEIVED WAS INADEQUATE AND MISLEADING TO THE POINT THAT THIS SITUATION OCCURRED.
