Minor stuff to give you more to research. It's the same for other countries also. To give you a few examples, the USA does not start with;
Coal Gasification (http://fossil.energy.gov/programs/power ... index.html
Common Missiles (self evident)
Depleted Uranium Munitions. (A political hot point, but I have used these)
Combat UAV (http://www.af.mil/information/factsheet ... sp?id=6405
These are just some examples. It is not an issue for me, gives me something to due in the begining of the game. I am sure most modern countries in game all have some like this.
