Yup, Google googles differently ...
depending on the country you are searching from. Found that out a few years ago when a Finnish cousin and I were searching for the same thing (in English). Has to do with databases and also filtering.
It's a really good idea if you're a grunt...

It is a very good idea because the Artillery, like the AF is into control and if they don't want to support you, they will not. I've had that happen way too many times and generally for extremely poor reasons. It's a good idea even if you aren't a grunt because it's a more versatile weapon.

I'll take your word that the 120s are more accurate, though in practice mortars seem to be more prone to error.
Wrong, mortars are generally less prone to error than the M101, M102 and the M119 -- however, due to micromanaging and nervous commanders, you find that of the three or four mortars in a platoon, only one gunner and one computer do most of the firing -- the best of each, 'to avoid error' (or embarrassment). Dumb, because it means the other gunners and computers don't get enough practice and therefor make a lot of mistakes -- that's your firing errors...

The 105 has a much longer effective range, especially with the RAP round, which is 80% more lethal (not that I would want to shoot it rocket off)
Not really that big a range advantage and the 105 is absolutely not 80% more lethal, the 120 has a larger charge. IMI and ATK are developing the M971 DPICM round.

I'd like to hear the argument for precision mortar rounds. Sure it might be fun to have, but with the HIMARS/MLRS and the Excalibur at seems like money better spent elsewhere. Especially since, and this may by due to the Copperhead, I'm not so psyched about laser designation.
You won't get it from me, I also am not a fan of PGM, particularly LGPGM. Too much money for too little benefit IMO.

You make some good points and I'll admit I'm not totally up to date on what is actually being fielded with the 120, but with 60s and 81s it seems redundant to me. Whereas the 105 actually fills the gap between mortars and the 155s.
Not really, the 105 range isn't all that great -- 11,400m (charge 7); 14,000m (charge 8); 19,500m (M913 rocket assisted projectile -- and my spies tell me that has accuracy problems) and with the new 120 rounds edging toward a 13 click range and a RAP in the works, the advantage of the 105 is fading rapidly, my bet is that it'll be out of the inventory within 10 years, replaced by the M777 as production of that ramps up and it gets cheaper; that and the NLOS-C.
I won't even address what too many charge 8 and RAP shots do to your tube life... ;)
Of course, if we'd bought the British L118 instead of the 119, we'd have more range and bigger shells but we had a lot of old 105 ammo in the depots and it was a $$ based decision.
The Marines have already or are in process of ditching their 105s and are buying Thomson Brandt Rifled 120s with still more lethal ammo, even better accuracy and greater range -- and it weigh a ton less than an M119. The M119 is reasonably accurate but not as good as a 120 and it doesn't have that much more range -- plus, my Redleg friends tell me it's a maintenance headache.
As for the other mortars, the 60 is too little to do much damage but it does have its uses -- it sure beats the AGLs. The 81 is better for many things but it will not lay down the volume of explosive the 120 can and has only about 50-60% of the range of a 120.
The 120 will do more damage within its range than the 105, it is more accurate, requires little maintenance and is going to get more types of rounds. -- and it's controlled by the Infantry Battalion. In Viet Nam, more than one Inf Bn Cdr offered to give up 105s in DS to keep his mortars when the Base Camp defense guys wanted the then 4.2 inch / 107 mm M30 which also outperformed the 105, not least on rate of sustained fire. Sustained fire has not been an issue in our current wars; it was in Korea and Viet Nam and you can bet that it will be again, sometime, somewhere. You should grow to love the 120 because it's going to be around for a long time while I suspect the 105's days are numbered. :D
The Armed forces of the US excel at it

It's what we do... :D

I'm not too stubborn to say if something is better than use it. But this seems to bleed into a discussion of the artillery's relevance in the fight. That may be a discussion worth having but going to the mortar seems like a back door way of avoiding it.
I don't think so, not really -- there is the issue of control but as you point out, that's a C2 / leadership issue that usually gets sorted out quickly. Mortars just give commanders more tools and they are flexible, portable, less ammo weight for equivalent target effect, have good accuracy and great rates of sustained fire.

By the way, the Marines got rid of the 105s YEARS ago, which was a big mistake at the time. They are getting the 120s, but those will be fielded by DS arty batteries who will be trained on both the 120 and 777, fielding the one appropriate for the mission. At least the last time I checked. :)
Depends on who you talk to, I guess. The Marine grunts I know have evinced no complaints. Though, having lived with Artillery operated Mortar Batteries in my misspent youth, I'm not a fan of the concept -- sometimes the Artillerist's proclivity for massing fires just because they can and whether its needed or not got in the way of DS support. ;)
Still, the Artillery and it's rules and relevance nor even the C2 stuff are the issues to me; the mortar's flexibility, availability and value are the important things.
