The British Army recently revealed its latest recruitment campaign 'This is belonging 2018', which featured an animated advert asking "Can I be gay in the army?".
The campaign has been seen as an attempt to encourage people of all backgrounds, regardless of ethnicity, gender or sexual preference to join up.
For the first time this year, the charity marked employers specifically on trans inclusivity, in addition to firms' efforts on lesbian, gay and bi-inclusive policies.
Ruth Hunt, Stonewall's chief executive, said:
"At a time when LGBT people are subject to profound discrimination and abuse, both in and out of the workplace, our LGBT-inclusive employers are a welcome beacon of hope that a positive future is possible.
Last year the British Army pledged its support for the LGBT community by becoming involved in the Stonewall 'Come Out for LGBT' campaign.
