I appreciate your well thought out and long answer, I got a lot out from it, thank you. Yeah I always forget to use grenades, and in either case everyone is so heavily shielded that they can't carry much of anything beyond their standard gear anyway. I prioritize TU always, I find that without everyone having good TU nothing really works.
The only point you make that I don't understand is #5, what is sell cost decline? Sales of what? The stuff I find on missions?
Oh, also, one thing I don't get about smoke grenades- if I throw it at an enemy and it hits them dead center, they are engulfed in smoke, and will suffer accuracy penalties or w/e. Question is, if I throw the grenade halfway between my squad and the enemy, does it work exactly the same, so that for instance one might smoke grenade oneself to make the squad harder to hit?
Also I'm having problems with assault on fixed positions, like the UFO, where I know there's aliens barricaded in there with overwatch and whatnot, and I lose at least one squad member per UFO breach no matter how I twist and turn it.
Lastly, if you will, please give a brief overview of how to properly use explosives when breaching a building. What are those satchel charges that every soldier comes equipped with by default, how do you use them? For what?
Again, thanks for taking the time!
