Yeah, once more, gonna have to say no. No they won't.
There's no reason they couldn't train in it just as well as a Jedi. In fact, the only things they wouldn't be able to do is deflect blaster bolts and retrieve a lost saber.
Err... what you can't do with a lightsaber if you're not Force sensitive (again, by Saga mechanics) is (leaving out things a Force sensitive could do with any weapon) ...
... block melee attacks over and above normal melee parrying, by using the force to anticipate attacks (block talent)
... deflect ranged attacks over and above normal ranged combat dodging, by using the force to anticipate attacks (deflect talent)
... redirect deflected ranged attacks at another target (redirect shot talent)
... construct and attune your lightsaber to yourself, making it easier for you to hit with it
... retrieve a lightsaber you threw immediately using Force telekinesis (throw lightsaber talent)
... become extraordinarily skilled in lightsaber combat (all the advanced lightsaber combat talents, most notably including the capstone lightsaber form talents, are exclusive to the Jedi and/or Sith preestige classes, which require Force Sensitivity to enter)
Now, you could make a pretty deadly lightsaber-weilding Soldier who didn't have any of those abilities. But because some of the best Eilte Trooper talents can't be applied to lightsabers, a non-Jedi melee expert is really better off using a more standard vibro weapon (and unless you've got a really high stregnth, you're better off using a ranged weapon). And as a bonus he can switch from vibroblade to electrostaff to vibro-ax as the situation requires, and all of his weapon-group specific feats and talents will still apply.
