They work perfectly well if used as intended, as said the one benefit they have over a squad is they are harder to detect.
The majority of my scouts normaly survive so long as I do not ask to much of them.
Trying to get all the way to a rear area or take out a tank help a unit in at tricky situation is what gets them killed. Urban warfare & jungles to but they are dangerous locals period.

A point & I may be wrong but scouts generally do have better chance to spot than a squad. Most scout units are in effect a squad the game has split into 2 half squads to aid it in said mission so man for man blah blah.
