Value of night operations

Quote by General Allen on night ops:

This last year we had about 2,200 night operations. Of those 2,200 or so night operations, in 90 percent of them we didn't fire a shot. On more than 50 percent of them, we got the targeted individual, and in 30 percent more we got the next associate of that individual as well...
In all of those night operations ... after 9,200 night operations, 27 -- 27 -- people were killed or wounded in night operations. That would argue for the power of night operations preserving life and reducing civilian casualties...
