General questions about the workings of Planetside

[Slab]

I just have some general questions (like the topic states ) about Planetside and it's game mechanics.

1.) What do jammer grenades do exactly? I was wondering because they're in the game but I haven't seen one soul using them. Just from the description; they stated that it resets the implant timer and it disables motion detectors. Why do that if I could just destroy the motion detector/Spitfire turret with a grenade? I'm not sure if someone was screwing with me but he said that if you throw it on a hovering mosq/reaver, it'll crash.

2.) Do my spitfire turrets/mines stay in the game after I die? What about after I log out from the game?

3.) I've noticed that when I enter the front of some bases; I hear a funny shrieking tone with a small radar icon at the lower right-hand side of my screen. Sometimes I see an icon that looks like a dot with lines underneath. Can anyone clarify on what this means? (tones / icons)

4.) I'm an infiltrator and I happened to see an enemy stealthier off in the distance (non-zoom). Thing is, he wasn't moving at all but I could see the name above his body. Couldn't see him visually but I could see the name in red. Someone told me that it is related to the #3 question I posted.

5.) Since I am an infiltrator, I was told that if I'm running...someone can spot me easily as if I was right next to them when they're in zoom mode.

6.) Last question and I'll leave ya'll alone. Assuming that an enemy infiltrator is nearby and he's not moving (can't see him at all visually without darklight). I heard that you can find him easily if you scan the area with the crosshair. Was told that when your crosshair passes over him, it'll turn red regardless.



Thanks for your time.
