1. Create test mission, 2 player slots, at least one vehicle that is considered artillery and the debug console available.
2. Load mission with 2 clients.
3. run code to add event handler that dumps output into a test variable, and watch the variable. (on both clients)
```
addMissionEventHandler ["ArtilleryShellFired", {
test = str (_this # 0);
}];
```
4. have a client get in and fire the artillery.
5. The client that fired has the test variable show the shell info, but the other non-local client will show <NULL-object>
