Hi All, I'm finding it extremely difficult to differentiate between the two trades: * Communication Systems Operator (CSO) * Communications Systems Engineer (CSE) I thought that the CSO deals with radio / satellite communications (frequencies etc) and the CSE deals with Data communications (LAN/WAN/IP/,Ethernet, RJ45 etc). My local TA unit that I'm interested in joining offer these two trades (going by their webpage) The recruiter I spoke to is a CSO, he did not know much about the CSE role and unfortunately the few CSE guys they have was unavailable at the time. What he did say is that the CSO has two specialism, FRR which deals more with Radio / Satellite / voice communications and CST (Command Support Team) that deals with Laptops, Servers, Ethernet, Printers etc He said that the CSO learn both FRR & CST but you can choose to specialise in FRR or CST (The later also does something called 'Rebox'(?) which is managing the data connectivity of loads of laptops, ethernets etc etc) He also said that the CSE role is going to be dissolved and be absorbed by the CSO, and most of what they do will be part of the CST side of the CSO role? A bit about me: I work in IT as a network engineer, so this involves routers, switches, firewalls, servers, cyber security, network protocols, IP addressing, Default Gateways etc. So I'm definitely interested in the data side of things and have very little interest in radio / frequencies etc. So if anyone is familiar with IT vendors, I'm a Cisco / Juniper / Checkpoint / Internet guy. So with that brief snap shot, what trade would you think is more aligned with what I do? I know there might not be a perfect match, so i'm looking for the on with the most overlap with what I do. Is it CSE or CSO. If it is the later, is it CST or FRR? In fact I think I'll list my questions below and if any CSE / CSO guys on the forum (other knowledgeable folks welcomed) can answer / validate my assumptions that would really help in my efforts to alleviating my confusions and choosing the right trade! 1) Core difference between CSO and CSE and maybe some details other than what is written on the Army website (Are my assumptions correct)? 2) Is the CSE role in TA going to be dissolved and absorbed by the CSO role? 3) Is the CSO role essentially FRR and CST or have I got my wires crossed or is there more here that I'm missing? /) What is 'Rebox/Rebok'? 4) which trade in your opinion is more aligned to what I do / what I'm looking for? 5) Out of curiosity, Who in the signals look after the network infrastructure i.e. switches, firewalls, VPNS, workstations, servers etc? I'm assuming when you deploy, someone is responsible for setting of a VPN from theatre to UK and configuring firewalls, an email server etc to do this? Surely the generals out there send emails back here etc or access resources hosted in UK or even the internet! Who provides that connectivity or is that civilian contractors? 6) Maybe some key content / material from courses that the CSO and CSE guys go on / learn. The CSO did mention one of the courses he did taught him about binary and hex which is something I'm very familiar with (sub netting, IP addressing). In my bubble of confusion I'm thinking the CSE role is more aligned to me, however if this role is truly going to be absorbed by the CSO, then the CST element is more aligned for me, however the CST at present is more 1st line, PC troubleshooting etc but again these are my assumptions based on information I've gleaned and I'm sure there many things I'm missing and hence my current confused state! Thanks in advance for taking the time out to read this and responding.
