Spade, that's exactly my point. Every optic has its advantages and disadvantages. I've used Aimpoints before and I currently use an EOtech and love it. Its great for limited use under known, controlled conditions, like competition. You turn the battery on, adjust the brightness, and you're good to go as long as your battery is fresh. If I was going into and out of dark rooms and bright rooms and wanted a big bright reticle for room clearing, the EOtech would be my choice. From a law enforcement SWAT standpoint it makes alot of sense because you know when there is going to be action and you generally have time to gear up for it to a certain extent. If I was a soldier in the field and wasn't sure when my batteries would be resupplied, if I had to react instantly to an ambush situation without having to activate my optics or adjust their brightness depending on what time of day the bad guys decided to ambush me, if I wanted a home defense gun that I could grab, aim and shoot without having to pause to activate my doodad sight, then the Trijicon looks alot more useful.
