It never ceases to amaze me how in depth people get with the game mechanics. I consider myself quite observant & watch what happens. As it turns out the human brain is a marvelous thing & when people say how does this work you realise that a basic understanding has been tucked away. You may well be right on search mechanics but for me personaly I want to understand the rudementary mechanics rather than reducing it very much to a game & taking advantage of the system underneath as this spoils the game IMHO. All to our own though but for the likes of me & simplicity moving bad, faster worse
For possible thought on your leap frog scout.
They are expensive compared to a squad & unlike a squad a 2 man team is nearly useless if it loses a man. doing this is subjecting it to danger so yes might only get one unload but at least the squad is more likely to be useful after.
I only say this because he is fast moving so fire at is dangerous & the question was how do I keep my scouts alive. I would suggest this wont help though agree on some maps you have to do something like this or make progress very slowly.
The question you should ask is will the possible loss of the unit be worth the info gained, if so its a go.
As a last point try & remember your lead units smoke status & if your vehicle has dischargers consider driving to expected contact point & poping them before unloading if no other cover is available.
