.RA2 has a prerequisite system, in which you can't purchase something until a prerequisite structure is present. Now, if you look up the rocketeer, it has this prerequisite entry:
Prerequisite=GAPILE,RADAR
GAPILE is the Allied Barracks, RADAR is ANY radar building. There's an and relationship here: you must have both GAPILE and RADAR to construct rocketeers.
So what qualifies as a RADAR? Defined here:
PrerequisiteRadar=GAAIRC,NARADR,AMRADR
The fisrt one is a generic Allied AirForce, the second a Soviet Radar, the third a special American only AirForce.
So, anyone with any radar and the Allied Barracks can make rocketeers. Case closed.
