This year's Army Servicewomen's Network annual conference will have the theme of 100 years of women in combat and they're looking for volunteers to take part in a photo shoot.
They are particularly keen to show different generations of women who have served in the British Army, ie a mother and daughter together.
Highlighting the difference between female soldiers a century ago and today, creating 'then and now' shots is also a possibility.
The aim of the Army Servicewomen's Network is to give female soldiers and officers a platform to develop and grow in their military careers.
It was established in 2015 to increase the number of women currently serving and improve recruitment and retention. A key aim is to make sure there is fair treatment on the promotion ladder.
Natasha Reneaux spoke to Major Melanie Crawford about how the role of women in the British Army has developed over the last century.
"Over the years a lot more jobs have become available to servicewomen in the Army... If someone wants to do a job and they're capable of doing it then there are no barriers on them doing that job and exceeding in it to the best of their ability."
If you would like to take part in the photo shoot email Major Crawford on RC-OpsEngt-Bands-SO2@mod.uk
