WO1 Brennan joined the Army 22-years-ago at the age of 23. He said: "My brother and sister served so it seemed the natural thing to do."
As a member of the Staff and Personnel Support Branch (SPS) in the Adjutant General's Corps (AGC), he provides administrative support to the most important part of the Army - its people.
Everyone is focused on doing whatever they can to support the NHS and everyone working on the frontline. WO1 Brennan
Like thousands of people across the country, WO1 Brennan is currently working from home as he provides administrative support to the units deployed, or on standby to deploy should they be needed, as part of the MOD's response to the coronavirus outbreak
He said: "The role of the 7th Infantry Brigade SPS team is to know when and where we have soldiers deployed to ensure they are receiving the correct pay and allowances. It's a very small cog in the bigger wheel, but everyone is focused on doing whatever they can to support the NHS and everyone working on the frontline."
Asked what advice he would offer his younger self he said: "I'm happy with how my career has gone so I think it would be to travel more when you aren't working; see more of the world out of uniform."
