SBR question

[dankoni]

I wanted something to ask about SBR's.Which units participate  in SBR's? My friend claims that he can defend with all units on his territory and
that  I can only attack  with bombers and fighters because it is not specified in the rules that he cannot do so.

I don't know the exact rules but on an SBR FTRs in the target territory may be sent up to engage the enemy BOMs and escort FTRs. Sending up interceptors is optional. If you do not do so only the AA guns that are in the target territory defend.

No other units in the target territory participate in the SBR. AA and FTRs if you choose.
