Stencil Font

Hello, can anyone help me identify this stencil font? It seems quite unusually rounded and I don't think it is a recent font. I apologise for the low quality image, it's all I have been given. Here's a link to the original image: https://www.bandmix.co.uk/mars-fortress/ It's for a friend who's brother was in the band and has sadly passed away, and he wants to use this font (or similar) in some memorial pieces. Thank you in advance for any help!
