Another question regarding basic rules

1. As I understand if a rigger controls the drone directly he uses: Ability (or reaction TN +2 as substitute) + Combat Pool (1/2 combat pool if using reaction) to attack
2. To evade incoming attacks control pool can be used against handling + modifiers
3. Special rules for incoming attacks : 1/2 power and reduce damage level.
Do the same rules apply for close combat when attacking / defending? Can a drone defend or only evade?
Probably the drone needs to be fit for h2h combat (arms / close combat weapons mounted) in order to make a counter attack roll. Otherwise we supposed it's considered full defense and same rules as above?
Thank you in advance for all the help!
