UPDATED April 2019: They appear to only be publishing anthologies now, and they often have open calls for stories for anthologies, but they are no longer publishing novels.
Cohesion Press is a small press publishes novels in the sub genres of military horror, military sci-fi, and creature-based thrillers. They have only been around for a few years but they have already published 19 books, although many are part of the same series.
They offer 50% of gross income on all electronic and print sales. They have a lot of detailed requirements so I recommend that you read their guidelines before submitting.
Their owner is Geoff Brown, the past president of the Australian Horror Writers Association. He also runs an editing company under a similar name. They are an Australian based company.
