If this guide helps you in any way then please respect my work, use a thumbs up on the guide and open my video on youtube + let it run:-)

This video shows the features of the game and shows the most efficient way to farm artillery kills.

Done with campaign and still missing some? This method might be obvious for some but if not it will be helpful for you.

Select multiplayer on the start screen, then select hot seat. Select 2000 points for the battle and start it. Choose the setups for both side, so if you want light tank kills select light tanks for both teams.

Start the battle and kill the tanks (destroying own tanks not count).

This is a very effective way of farming as if you kill Axis tanks as Usa the kill will count, then you move with an Axis tank and kill an Usa tank, well, yes, that will count too. So this way in one battle kills for both side count.

You cant do this in hot seat mode as you will take damage at least on one side. The easiest way to do is to play a custom battle against the AI, give only 1 light tank to the AI and try to destroy it without suffering any damage on your side. As AI not using the explosive ammo (so no collateral damage) this shouldn't be hard.

Both air strike and minefields are useable cards if looted up. You can find green lootboxes on the map. Moving any units close to these boxes award you an action card, which might be a minefield or air strike or any other from the 6-7 various cards. You need to use those cards in that battle, you cant save up for the next one.

3 Air Strike cards available every time the enemy attack one of your provinces which has an airfield.

This is the most annoying achievement and I believe this is the reason you here. Artilleries not selectable for custom or hot seat battles. You can face artilleries only if you attacking enemy territory. There will be battle only if an enemy unit station there. Additionally, not all provinces have artillery units so it would be time-consuming to farm these during normal gameplay. An additional problem for farming it during the campaign is that you need to spend times for defending. During a defensive battle, you can't score any artillery kill.

So what is the solution? (btw, it's in the video too)

1. Start a new campaign without any unit deployment and play as the USA
2. Produce 5 light tanks at Southern Italy.
3. End Turn
4. Feel free to produce additional tanks if you wish, but 5 should be enough.
5. End turn again so axis can move at least one unit to the Gustav Line (germans usually moves there only 1-2 transports)
6. Recon Gustav line to check if there are the required artilleries or not (in case you missing now only light/heavy artillery kills)
7. Attack Gustav Line from Southern Italy with your 5-6 light tanks. Don't send 2 transport units with them. This way you won't annex the province and you can repeat the attack in next round.
8. Rush solve the battle, could be done in 4-6 mins for 3 artillery kills. Repeat once axis moved there again one unit, it will be likely again a transport unit, or
9. Start over from point 1 if Axis already conquered undefended England and now moving armies to Italy or Axis don't want to move armies to Gustav Line.
