(KCEN) -- October 7 marks 12 years since the U.S. invaded Afghanistan.

And the anniversary is of course being overshadowed by the federal government shutdown.

54,000 American troops remain in Afghanistan.

That is more than at any time during the first seven years of the war.

Four were killed within a week in so-called insider attacks just at the end of September.

102 U.S. Troops have died in Afghanistan as of October 1.

That's more than during any of the first six years of the war.

The military is whittling forces down to approximately 34,000 by February and the number of coalition bases has gone from a high of 800 to about 100.

But combat troops will be there for another 15 months.
