Ummm... let's see... USF has CalliOP and Priest, incendiary attacks, pack howie, of map artillery;
UKF has Sexton, base howies, off map artillery;
OH has PZwerfer, howie and off map artillery;
OKW has wurframen and off map artillery;
Soviets have katiushas, howies, B4 and incendiary attacks.
Did I miss something?!
Well you should not get your mortars to close, because it's dangerous. In fact, don't get any unit to close, because it's to freakin' dangerous. Is that a reason?
If you don't want to use mortars, fine, pick one of above, at your liking.
USF artillery... calliope - locked in doctrine. priest - locked in doctrine. incendiary attacks... do they have this? i only recall white phosphorous (in which case does 0 damage towards buildings), off map artilleries are 8 cp+, heavy munitions drains, require LoS.
UKF has SUXTON and LoS, close proximity obvious red flares with super poor accuracy base howitzers, off maps are late game and I think only 1-2 commanders have one that damage buildings. You can refer to all the other threads on how horrible these artillery units are as well as doctrinal suxton
OST has panzerwerfer that squadwipes very easily like calliope but it is non-doctrinal...
OKW has stukas, incendiary, and arty (doctrinal)
SOV has the most balanced rocket artillery katy, howitzers that get one shotted by globals, b4s that require RNG god's blessing... who ever builds these anymore... and quite a few commanders has incendiary.
Only issue I have is that... do I have to pick a doctrine just to counter FRP? I won't have artillery unless i pick one of the two USF commanders and one is paid... USF FRP is pretty easily destroyed by small arms. ambient fallschims could do the job. that OKW HQ, given that it's a HQ, isn't easily destroyed. It's not like an OST bunker where a 3-4 AT rounds do the job. I don't know the amount but it's pretty durable i'd say at least 12+ AT rounds
