@FARTED99 you would find out on later levels that sending masses of your troops all at once is just pointless. You send as many units as possible only if you are certain that you will reach the portal or if YOU HAVE TO DEFEND YOURSELF. Thats exactly what computer is doing! BTW. Wishing anyone to die in a bus shelter is not very kind :/
