Sorry last time I am going to say something but please try exploring diffrent things in the game & grasping how they work, you may well find you enjoy the game more for doing so & certainly will become more effective at commanding your units.
I am refering currently to scouts.

You are all for getting your experience up so your troops perform better but you are wasting your scouts who probably 2nd to FOOs are the guys you want to improve for an easy game. At least they are in your core

Scouts will inevitably die as its not the best job going but what is his role.

To observe & sneak around relaying info & to aid this hes a tricky guy to spot.
Most start with a 3% exp bonus so he sees very marginaly better than a standard squad. Sometimes seems more as should be moving cautiously if a threat is likely.
Now what happens when his experience climbs
He gets an extra shot & more chance overal of hitting but thats not very important.
What is important is he develops a knack for knowing where the enemy are & seeing them. Hes also developed his stealth skills a bit more & manages deep recon like RERomine mentioned without biting the dust.
Of course if a choice target comes into view he can use all his skills to close & take it out if need be.
He is in fact a bit of a catch 22 unit in that you want him to survive & become proficent at the job but when he is risking him in woods & the like leading the way becomes hard to resist because he has an edge.

Sorry to be a party pooper but if you take the time to explore the game you will find you missed half of it. For instance you have not even loaded a map, what about the map generator to tailor the map to what you want, combined arms the list goes on & on.
Learning by doing is also far more effective than asking or making assumptions.
