OK Here is my Tactic.
For later in the game on Dust, when the enemy are approaching your base with tanks.
Take 1 bike
go pickup a sticky mine. Place all three mines on the front of your bike.
Wait for the mines to respawn then collect them.
Ride at full speed to the tanks try to get in close but don't ram it . All the mines jump from the bike to the tank, boom.
Some players were getting wise to this in the beta, and would jump out of the vehicle just as you arrive.
If they do , then just fire the three mines you have onto the vehicle and drive off.
As soon as they get back into the vehicle , boom.
Fed up with your base being torpedoed by hawks ?
To use the torpedo properly, hawks have to fly in a low strafing run across your base.
Place three mines in the valley between the two peaks by your base, as they begin their strafing run, the mines will jump up and attach themselves to the hawk. Boom.
WARNING you need to be skilled on the bike to ride round with mines attached, as a single near miss from a tank will take you out.
Not really a tactic. On most maps when you spawn, if you really push that stick you can normally land somewhere you can get a clear shot on some Barrels of Turquoise goodness giving you 4 units within seconds of the start of the game.
As we all know and sometimes hate, at the beginning of every game about half the team jumps on sidewinders and try's to capture each other's flags. The problem is, everybody is going so fast you really have no way of combating them at the beginning of the game. Well look no further. First go ahead and save one rift and grab a bike from someone else's corral. Then, grab some proxy mines and stick them all over your sidewinder. Now, instead of trying to stop and shoot the speedy devils, you just ram into them and they blow up.
I'd like to give credit to whatever genius did this to me on dust. The stupid ones never win.
