The reason for the missing crosshair is your video driver. check your video card and operating system version, and then update your driver. just go Google it, it's no problem.
if above does not work, maybe someone has made a MOD(game enchancement) that fixes the problem. (Google tags: bf Vietnam crosshair mod fix etc.)
You buy the game then it will appear on on the home screen and you click it.
The dog tags do appear when you melee/knife kill someone in Battlefield 3, you just have to look really closely. See related link below.
Laser beams already appear in battle. They are not weapons themselves, but are used in ranging and targeting other weapons.
The 'Leafers' appear in Lethal Weapons
The world is leveled so eventually around level 18+ the most powerful weapons appear on enemies and in stores.
This does not appear to be a supported function of the game.
Yes, but they appear only for the weapons. all i know is battle codes and they are 24bx3a,288288,33ax28
I don't think you can lay down in Battlefield 1943. I think you can only kneel.
No, you cant make your own weapons unfortunately. Jagex makes all of the weapons but if you wear the right outfits and stuff with some swords that may appear to be a light saber.
If you swim close enough to a shoal of fish or another monster, either a pair of crosshairs or a health meter will appear. When this happens, press the B button to attack. Although, I may advise you by telling you; don't attack something you can't kill such as a tylosaurus.
Lots of possibilities here. My favorites, in no particular order: 1) politicians could not appear to be as "soft on Communism" by "losing" Vietnam; 2) the doctrine of containment required us to become involved; 3) it was believed that if Vietnam "fell," the rest of southeast Asia would follow.
This is a purely subjective observation: most of the Vietnam War era media illustrations I've seen appear to depict the futility of that conflict, in one way or another.
