When googling "Artillery Field Officer" or "Joint Operations" very little CoH2 related appear, so I have to post here.

I thought that the Officer's artillery ability ("combined something...") became more useful as recharge time of the Panzerwerfer and Lefh 18 became worse but I often still find the artillery pieces ready to shoot when I need it, so in my last test game I had to be quite trigger happy if to exploit the Officer's artillery ability.

Furthermore the artillery ability seemed to work no matter how far I moved the Officer from the artillery pieces - they also seemed to shoot further than their normal maximum range. The Panzerwerfer also didn't move to stay in range of the target I think, but can people back this up? Also, how close does the Officer has to be to the artillery pieces?

On a great 6-8 players map the artillery pieces all shot every time I used the ability. Will try another test game where I place them in my base and use the artillery ability in the enemy base.

It was quite overwhelming to use the ability and see the combined fire power of 2 Panzerwerfers and 2 LeFH 18 artillery pieces land at one spot just after I used them individually elsewhere on the map - of course the rest of my army wasn't much.

Does anyone successfully use the Artillery Field Officer and/or the Joint Operations commander?
