Re: why can\'t you trade specific techs?
Actually, giving them 1 level of Warheads increases their level in Warheads by 1, up to the max of what you have. So, if they have Warheads 1, giving them one level in Warheads will give them Warheads 2 (assuming you have 2). Giving them 2 levels brings them up to Warheads 3 (assuming you have 3).
