sorry guys f&#@ing keyboard playing up.
I use CoC Arty, and its very powerful with the right scripts but it is also a pain in the arse to get use to. It is also very script intensive on its own so unless you have a good system you will get lag in missions with LOTs of troops.
I have a mission where 4 M109 platoons + 4 M101 platoons and 4 mortar sections are on call, enemy has 4 2s1 platoons + 4 2s19 platoons on call (might make 82mm mortars for them and let them have them). The AI will call in arty when enemys spotted and freindly units arent in range, and US side has MRLS on call( and if i ever get a BM-21 or similar working east will get the samething maybe) if they come under arty fire themselfs. With a couple of extra scripts they ALL use shoot'n'scoot tactics(execpt mortar atm cause it would require another bloody script) and i have so many troops + armour + air support it lags pretty well in some cases. But this as i said has taken a very long time to make and is very script intensive so choose carefully. Most cases you probably better using basic arty script where you want it to fall, i just made that mission cause i wanted to try to recreate a more atmospheric battlefield(and with ECP + surround sound on its very intense and fun!.
