easiest way to find class names that ive found is to put the ones you want into a mission, save it, find the mission folder and open the missions.sqm in notepad, thatll list everything that has been added in there with their respective class name, for example:
<table border="0" align="center" width="95%" cellpadding="0" cellspacing="0"><tr><td>Code Sample </td></tr><tr><td id="CODE"> class Item56
{
side="EAST";
class Vehicles
{
items=2;
class Item0
{
position[]={18654.742188,11.970000,14497.184570};
azimut=135.000000;
special="FLY";
id=140;
side="EAST";
vehicle="mig15bis";
leader=1;
rank="LIEUTENANT";
skill=0.600000;
};
lookin at this you can see the class name for the mig15 as vehicle="mig15bis";
