> The systems that Russia and China are known to be developing or have already fielded include destructive and non-destructive types that are deployed from Earth, such as ground-based jammers, lasers, or interceptors, as well as small "killer satellites" positioned in orbit. A killer satellite able to maneuver close to its target could use various means to try to disable, damage, or even destroy it, such as jammers, directed energy weapons, robotic arms, chemical sprays, and small projectiles. It could even deliberately smash into the other satellite in a kinetic attack.

Also, how do the US military's capabilities inform us about what other militaries are doing?
