Activate trigger by unit type

[bobrock011 10]

How do I get the trigger to activate to specific unit type, such as armor? I do not want to use unit names or grouping with the trigger because enemy units are dynamically spawned in game. How do I get trigger to catch these by type(class)?

Thanks for any advice!

The first works on general types of vehicle such as "tank","car","landvehicle","air" ect

{_x iskindof "tank"} count thislist >0

This finds the actual vehicle type "M1A1" will only work on the M1A1 tank

{typeof _x == "m1a1"} count thislist >0
