How to deal with late game arty spam

Hi! I'm pretty new to COH2. In 1v1s, I've gotten really close to winning (50 points away), only to have the ever living shit blown out of my spawn, any units, etc, with rocket arty, regular arty, and heavy armor to back it up. I of course have my own heavy armor (I play as the US), and do what I can to try and take it down, but I always lose fights to tigers + arty + blobs of AT infantry, then promptly get my spawn camped to high hell by constant artillery. Is there anything I can do/do differently?

Hi man, welcome!

Best thing you can do is probably upload a few replays of you on coh2.org in the replay section and link them here if u want some indept feedback. I myself am not really a 1v1 specialist, more a 2v2 main. What i would do however, in the first place is get some arty myself. Pakhowis are amazing, but scotts will also do if u want to be more mobile. Mobility and not blobbing (to much) is also key, since people have the tendency to safe their rocket arty barrages for that one big fat target.

also you should try to prevent your axis opponent from getting to this point of having arty and heaevy armor at the same time where u can. (easier said then done lol) But what i mean is that you could go for some sneaky stuart/sherman rushes and try to sneak up on a pwerfer. You could even give the stuart crew some zooks if u got ammo left and just pop out next to the raketen. since a stuart wont 1shot a pwerfer but 2 zooks will i believe.

probably more 1v1 gods will show up here eventually to give more tips.

GLHF on the battlefield

The problem might be, that your opponents tend to play very passive with larger armies then you your best bet against blobs of at infantry is your own infantry ideally with bars, lmgs thompsons or a few .50 cals (which might have more troubles against artillery but can fend off bigger groups of enemies for their cost).
In some cases it might be useful not to mirror your opponent and maybe go for asymetric warfare by getting a medium tank and a tank destroyer against an axis heavy tank and this wouldn'T lock you in the heavy cavalery doctrine and allow you to get some p47s to deal with a potential tiger or getting a mortar halftrack maybe in the lategame a own calliope or the time on target artillery to counter axis artillery options or to appl some pressure on the blobs or forward/defensive positions.
There are many different factors and it migth take some time to find strategies that you like to play and work well enough in countering whatever is bothering you. Posting replays and asking for help in a few specific situations or just rewatching your replays and checking for popcap, ressource control (mapcontrol) and management (float) or just minespots weak spots and general engagements might help you improve by a lot.
