> i can't figure out how to use it, do they throw it automatically when in range ? can it be thrown at building for demolition purpose ?
They do it automatically at close range. I've seen them throw it. The projectile is very hard to spot - look for the small triangle with a smoke trail, just like the grenades.
> the new recon team has thermal aswell as some tanks, what does it do ? does it see enemy through smoke ?
Thermal only lets you see further/ID faster, I think.
> it look like we lost some vehivules like the k-115 replaced by the k-115v and k-115a1, aswell as the k-50a.
The K115A1 is exactly the same as the old K115. The K50a does seem to be gone from the player's inventory, but I've encountered some in game so I'm assuming it's just not being made available to the player at the moment. (Like the variants of the K75)
Is mahiri's reload bonus supposed to effect autoloaders, or just manual loaded units? It's hard to tell, partially because I don't know what ranges it kicks in at.
If it does effect one but not the other, I feel like that should be mentioned somewhere in the description.
