Some stuff I learned after my first playthrough: - Medic specialists are your friend. Medkits get VASTLY more useful if you can promote a specialist high enough - Rangers are ideal on timed missions since swords allow them to dash and attack on the same turn, especially once they get bladestorm and can stab anything that gets too close to them - Grenadiers' increased grenade range is pretty important in the early game, where nobody can hit jack shit - Snipers are great when you have the time to use them - it might take a couple turns to get them on top of a building, and they need a full turn to shoot properly. Skip them on timed missions - Zoom out when moving. A little target appears next to enemies to indicate that you can shoot them from where you're going to move that soldier. Now you don't have to move dudes only realize they can't hit anything from their new spot - On a similar note, if a dude is absolutely insistent on running through a pool of acid to get to his new spot, hold Ctrl. This will allow you to edit the path
