I thought it was more limited to the engis, but i have found that colour blindness could potentiall prevent me going into the signals as well, i have had a few informal interviews and am going to have a chat with a TA sig tonight. Basically what am i restricted in? what cant i do? im likely cp4 colour blind, but maybe cp3, never done the lantern test but im abysmal day to day and in the plate test. ideally im looking for something like: Information Systems Engineer - ARRSEpedia or Installation Technician - ARRSEpedia I want as many skills as possible which will transfer over to civilian life. would also consider electronic warfare operator/specialist operator anyway i will likely get a comprehensive colour blind test from my optician asap, only had basic plate ones before and have not been classified. I score like 1 or 2 on the plate test. thanks. and hello all!
