The Army does not use Leupold exclusively. Sniper rifles in our armsroom have S&B, Nightforce and Leupold scopes. I have been active duty for quite a while now and am fairly familiar with all of them (Not much time on a 2010 or with the S&B).

RDFinn I agree with Formidilosus that the Leupolds are the most problematic of our scopes. The MK4 LR/T 3.5-10 M2 that come on the M110 are the worst.
