The bombs are thrown from fighters, while guiding by laser beams from snipers. Bombs can be thrown in any altitude (and deal damage), but a snipers can only guide the bomb within 200 meters from his targets, and he can't remain stealth when guiding the bomb (rule: one can fire far away, but there must be a way to counter it within range).

The bomb will act like a free fall bomb when not being guided, but with a certain degree of Brownian movement, which makes it hard to hit target without guiding. But there leaves a possibility that the sniper guide not full time while the bomb is falling, but a certain part of time (like if the bomb is close enough to target, there is no need to continue guiding of course).

The bomb thrower and the guider can set a 10-bits number in their weapon, (like 1234567890), only the same coding makes the guiding works. If you managed to get your opponent's secret number, you can guide or at least misguide them. And if multiple planes and 1 sniper have the same number, the multiple bombs will be guided to the same location directed by the sniper.

For balance, the ammunition should be limited, the fighter needs to go back and add ammunition repeatedly, which makes it a short time burst tactical weapon, which can't deal damage continuously.
