Just on the test range tho? On the MP map Paracel Storm they can be destroyed.
I just got the last jet master dogtag, equipped one and the new contrails are totally worth it... a slight blue tint I think. That is all.
On the test range it used to be metal sides and wooden struts across it, now its all concrete. Just seems weird they would change it on the test map, not sure if its been changed in paracel or not.
