Taking in consideration the observations just made by akdavis, which are absolutely true, my new suggestion would bë:
- Seeing a tank lossing its turret because of the exposion
- Seing a moving tank get its track (i think it the right term) get broken and start turning, until finally stop and be abandoned, if the crew is modeled.
- Seeing vehicles and objects being thrown in to the air due to explosions.
- If a ship explodes, parts of the ship being blown away in to the air.
- Trees being thrown away in radial pattern from the center of an explosion.
