I know what you are thinking! You think: Oh F##K NO! But still read this pleace!
First of all, i am fairly sure this will never be implimented, but i thought that aliens hawe 3+ species at theyr disposal UNFAIR!
So how if we would add man`s best frend to fight for man???
Basically dog would be WERY fast unit ideal for scouting, (possibly capable of smelling enemies behind corners???) It would be significantly weaker than its human counterparts: (Plasmapistol hit would end its misery) And good melee fighter (though only against UNarmoured targets) It could possibly need a (dog quarters???) -room and would enable research of dog armor (although dog armor would only go as far as nanocomposite -They are just DOGS anyway!)
In general:
-Wery fast (40 - 60 TUs
)
-Wery weak (50 - 65 HPs
)
-Possibly capable of smelling enemies at a distance of 5-8 meters???) (small distance to keep it fair!)
-Powerful melee attack against unarmored targets, though useless as a combat unit on mid to late game.
-Capable of howling/barking/growling to scare enemies???
Some other animals instead/along with?
?
