From reading this quite a lot of people don't fully understand the permissions of RRD and are +1ing for the sake of it. I understand a lot of hatred is directed at RRD due to certain people who are gone. Hopefully this will clear it up and reassure you they are currently being looked into.
No not every single rank in RRD get an extra weapon it is only the Medical Corps Command that get this.
I no way does RRD make either of those weaker and RRD do not get to use any piece of equipment. RRD get significantly less than every rank you have just mentioned there, SCO and FMO & HRO both get the additional 1 weapon of their choice per event, however we have limited the equipment that RRD may use, whereas an SCO has more to choose from and an increase in HP.
Medical Corps Command is equal to that of Battalion Major, they receive the same amount of extra equipment a Battalion is allowed and have significantly less HP. The Head Medical Officer is equal to Head of Battalion he may use less extra equipment the HOB can use and has alot less HP.
This one instance used an example was a new temp confused with the rules on the number of equipment he may use which resulted in his high kill count, he has now been informed of the correct amount he may use. Medical Corps Command is something alot harder to reach than regimental hierarchy, the application alone has incredibly high standards set as a requirement and applications for a position open rarely and out of the many high standard people apply only 1 is chosen by High Command. This is why they are equal to Battalion a receive this one extra piece of equipment.
High Command are currently reviewing the powers that RRD have and there will be changes implemented soon, however the current weapons are not a subject that requires change. All documents on RRD are available in High Command announcements I'd recommend reading them to get a full understanding of what RRD can do.
