Military strength of Numenor

A big enough number of orcs could give the Númenoreans "a lot of trouble" but I don't see why a decent number of Númenoreans wouldn't be able to overcome trolls or even dragons (or some really heroic or lucky individuals hitting the right spots - like Bard managed to kill Smaug much later ).

Whether they could have matched with Balrogs I think is a bit harder to ascertain as I think it comes to the "mind-bussiness" of which we seem to know somewhat little about. The Great Elves of old stood their ground against Balrogs, the Dwarves did, Gandalf did (even if it always meant death to them as well)... but the Númenorians? My gut feeling would be yes, they could have stood against them, but well, that's speculation.

To elaborate on what other posters have said, particularly Mith and Legate, I think if you are going to make comparative assumptions regarding an army plopped into another Age of Middle-earth, it must be done in context, and with the baggage train they carried.

For instance, if you are speaking of a Numenorean army, which one precisely? If you are referring to the armada of Ar-Pharazon, I believe it would be likely that they would have already been seduced by Morgoth and turn on the Elves. Remember, many of them already worshipped in the cult of Morgoth. Beyond that, the corruptibility of Men is well documented throughout Tolkien's corpus. And as others have stated, Morgoth had an eternity to work his wiles.

But aside from context, in reality, no Numenorean army would do anything but delay the inevitable victory of Morgoth as pronounced in the Doom of Mandos. It was a no-win situation. Defeat was ordained. And really, the Edain that fought against Morgoth were if anything just as powerful a force as the Numenoreans. They were their ancestors, after all.

This seems like the key here. There's an almost universal theme in the Silmarillion, it seems to me, of "fading:" all good things must come to an end, and everybody falls eventually, so it's doubtful the Numenoreans could have done anything the Edain didn't.

That said, there is a little leeway, since there's a fair bit of emphasis in the Akallabeth, it seems to me, on how great and glorious Numenor was before its decline, but it's still doubtful that they could've done anything especially huge. Legate and Galadriel55 have already made the same points on the topic I would - any battle against what I would term a "high" creature, such as an Ainu, must ultimately come down to spiritual power, not physical, whether that be the purity to avoid corruption or merely the mental strength to face such a one down.

I think the fading usually is with the Elves whereas the age of Men is waxing. I believe the Numenorians were greater than their Edain ancestors. They are said to be closer to the Eldar than to men; "in all things more like to the First-born than any other of the kindreds of Men;" [Sil; 321]. Now their power did wane due to their rebellion and desertion of Eldar-like lifestyle. That's why the Kings in Numenor were only living like 250 years whereas the Faithful still had greater lifespans. Elendil was over 300 when he fought Sauron. Ar-Pharazon felt his end coming when he was about the same age of Aragorn when he died.
