It is of :paramount importance to preserve a common-sense outlook 

towards the subject of security. The ideal is the indoctrination of 

all personnel to the point where they are conscious of the security element involved in the routine discharge of their duties. The protection 

of classified information must be an integral part of each task and not 

an additionally imposed burden. The attainment of the desired objective 

requires sound direction by those in responsible positions and alert 

perf'ormance of duty by all subordinates. Ref'erence para.graph 4b, AR
