Suggestions:
higher damage more radius on advance granades and a 1 round delay for the Grenades so that the AI will move from a cover or empty a room incase it senses a grenade that is in radius. Then you can use your troops to make them attack with reflexes while enemies are moving.
Armor shows the what kind of defence its showing, Rear, Front and back just like the tanks do. i guess this will be available when the armor value is known to be set.
If not implemented? that the AI will have less Reflexes while not facing you and viceversa.
Training facility for late game troops ( saw this somewhere as a suggestion though just want to remind )
Medic facility to be a research option first because i often build the facility as a must option in any case.
a cheap scout plane with more fuel and radius that is used to spot a UFO when a event happens. Maybe could fit in a garage instead of a hangar also and that the garage will be cheaper.
the problem to send you normal planes to a event is that they will probaly not reach or have fuel left to fight if its far away. If you do so anyway there is a high chanse that a Ufo will get spotted close to your base just when you sended your ship far away or is home fueling up.
if you have your last base selected it will show the fuel levels of your plane in a corner or so to se when your planes are fueled up and ready to send out instead of constant clicking to see when they are at 100%
Remove stun grenades/missiles and Save stun baton and add a crossbow with tranquilizer darts or a short range stun pistol.
Indoor Aliens?
MORE accessories like mines, night vision, short range scanners, Enemy mines, mine sweeping tools, Door blocker, Door passing detector, Mini Grenade Launcher, Laser Spotting device for greater aim, guile suit Camuflage ( while crunched down and not moving you will not be seen before shooting).
Combat Knife or rifle but attack animation while closeup
All this must be implemented or i will kill myself.
