Query: Reggeon-gluon vertices with Ward identities   Ward identities for reggeons are studied in the framework of effective action
approach to the QCD in Regge kinematics. It is shown that they require
introduction of new contributions not present in the reggeon diagrams
initially. Application to vertices RR$\to$RP and RR$\to$RRP are considered and
diagrams which have to be added to the QCD ones are found.
