– Near future, distant future, alternate reality… These are some of the settings in which we get to ask the question of “what if?” The problem is, realistically projecting forwards always requires a solid understanding of the present. Parabellum doesn’t just know weapons, we understand how they work and how that information can be used to create incredible immersion in futuristic stories.
Whether you’re looking for advice on props, visuals, language or even the supporting science, we can help.
Our expertise extends beyond an individual nation, emphasising a global reach rooted in extensive knowledge and research capacity. Military domains and doctrines function as universal languages, defined by alphanumeric nomenclature, standardised technologies, and both time-tested and adaptive strategies. While it’s possible to intuit basic expressions easily enough, true fluency demands years of focused study. That’s where we come in. Contact us today to discover how we can support your project.
Why Parabellum Advising?
The world of weaponry is diverse and extensive. With it comes the opportunity to exhibit its numerous facets in visceral fidelity for cinematic or storytelling effect – an opportunity that is far too often missed, usually for lack of knowledge. For example, most depictions of crew served weapons, usually with an explosive component, are inaccurate and comparatively underwhelming. In this sense, and in the context of audience experience, fact is almost always more desirable than fiction. Make sure you never go without the right military advising again with Parabellum.
Why it is so important to get it right
Gone are the days when war footage was exclusively shot by state sponsored embedded camera crews, providing only short glimpses into the operations of warfighters. Now, hour long clips in 4k can be shot by anyone with an inexpensive action camera coupled with a picatinny or VAS helmet mount and posted on social media for all to see. Combined with an ever-increasing consumption of, and demand for, realism in military centric media, the bar for excellence in film, TV, gaming and literature has never been higher.
Moreover, with the rapid evolution of modern weaponry and tactics, staying accurate and relevant requires constant attention to detail and ongoing research into increasingly complex systems.

Introducing Your Military Advisor
Founding Parabellum Advising in 2024, my vision is to apply over 15 years of personal study coupled with 4+ years of professional experience in the world of defence to the entertainment industry.
Prior to Parabellum, I worked for a defence manufacturing company in Glasgow as a sales manager and subject matter expert in weapon systems. With a sister company in the States responsible for North and South American contracting which were also within my remit, I was exposed to numerous high-profile opportunities that required extensive technical knowledge. Standing on a uniquely formed foundation, I was naturally able to apply over a decade and a half of passionate self-study in all things defence within a professional role. Over four years of consistent hard work led to many instances of significant success, ranging from advising end users on their various equipment needs, shaping and subsequently delivering complicated UN Security Forces equipment orders, and representing the company at industry trade shows and important client presentations. When relevant, this work was done under strict adherence to ITAR and other export control legislation and in close concert with multiple stakeholders, further refining strong communication and teamworking skills.
Looking for a new way to leverage my unique capabilities, and with the promise of fresh challenges, I am excited to launch Parabellum Advising for the global entertainment industry.
