Theres a reason droids were always killed in Star Wars and no i have never watched any of the terminator movies.
Oh man, how could I have forgot, we cant use unmanned machines...the enemy is training Jedis. Im glad you caught that.
All im saying is the military said they will never eliminate human soldiers and as a wis eman once said"A soldier doesnt fight because they hate whats in front of them,a soldie rfights because he loves what he left behind."
Good quote, and I pretty much agree, a full on replacement is highly unlikely. But I believe un-manned tech will become much more prevalent than it is now.
