The best way to take the pressure off our troops is to succeed in Iraq, is to train Iraqis so they can do the hard work of democracy, is to give them a chance to defend their country, which is precisely what we're doing. We'll have 125,000 troops trained by the end of this year.
They are going to get 120,000 + 5,000 troops 
120,000 + 5,000 is 125,000 troops. Which is the amount said to be gotten/trained. I think the model got confused by having to add addition.
