When you're all finished, your CO can quickly total the amount of green,

amber or red equipment in the whole outfit. REDCON .•. REDCATYour commander includes that in a Unit Readiness Report to higher headquar.t ers. There's lots more to it than the equipment profile-per cent of TOE strength, training status, critical MOS strength, AIT resuits, IG report, CMMI resuits, technical proficiency inspections, participation in major field exercises, specialized training, presence of prescribed supply loads, POM- all go together to measure the Readiness Condition ( REDCON) of your nnit. This is measured against the Readiness Category ( REDCAT) that has been assigned to your outfit. Under REDCAT, different units are expected to, be at different stages of readiness . A line company sitting on a border someplace, for example, will have a higher REDCAT expectation than a newly organized support unit ba~k in CONUS. Not to low-rate CONUS outfits, though- a STRAC unit in CON1JS might have a higher REDCAT assignment than a similar tank company in the Pacific. REDCAT says: Your outfit is expected to perform to a certain level of TOE

~~ .,",••,,~, ., ,," , .. >00 .. ). ••

~~~~~ REDCON is the measure of what your outfit is really capable of doing-and how long it can continue to do it. (AR 220·1 has all the scoop.) The measuring of readiness is a tricky business. Most any trooper will answer quickly: "I'm ready, and so's my gear!" The first reaction of any commander is: "Can dol" But enthusiasm i~s tricky, and emotions are not based on facts. Also, modern warfare demands dependable equipment and men, together. That's where you and the ESC enter the unit profile picture.

Like a "Morning Report"One way of looking at it is to consider it an "'equi pment morning report." Since the days of Julius Caesar, the morning report has been an essential part of the information that influences command decisions. Its purpose is still the same-to tell the commander what his losses have been, what his effective strength is, and what kind of a chore he can cut out for himself for that day-with a reason-

There's no doubt about it. From the time a new rotor blade is uncrated, until it's shipped back to overhaul, it needs a lot of extra care . . . the kind only you can supply.

Seems like the replacement and retiremen-t schedule in the organizational maintenance pub has a replacement time of 1000 hours on some of the transmission mast assemblies. But that was before the mast bearing in there started to act up. Bearing, pIN 204-040-136-5, just doesn't have the stuff that good bearings are made of. So the TWX says the mast assembly on your bird now gets 22

replaced at 400 hours, and the bearing is retired for keeps at the same time. Para 4e(l) ofTBAVN 23-10 (18Sep 62), on accessory changes, doesn't let you go past the 400 hours, either. The mast (and bearing) TBO is even less-200 hours-if you're in the area covered by TWX SMOSM-ELUH-l-081500 (23 Aug 63). But no matter where you hang your cap, be sure to make a special check of the transmission primary oil filter and the magnetic drain plug every 10 hours, for metal chips.

well-the 'mast assembly bearing may be on its last legs for real. Of course, the bearing picture can change, what with a new, improved bearing, pIN 204-040-136-7, in the works. That's why it pays to kecp the speNaturally any metal chips mean that cial inspection and the replacement and the bird's probably going to wind up retirement schedules up to snuff. Who at support for a disassembly check. And knows, maybe some hot poop is coming if those chips in the filter arc bronze-- over the wire right now!

The intermediate inspection in the Sioux (OH.13) TM 55·1520·204·20 (6 Feb 62) calls for checking the 450-500 in-Ib torque on the tail-rotor-drive-shaft - . . ,......,-. .-"..L_--=::::~:J lock-nuts, PiN 47-644-035-1, in area
