Maintain Skills Through Staff Turnover

Calian has developed a training system for NATO NFS HQs where there is high rotation of staff every year, with almost a third of staff being replaced during the summer months. As this makes maintaining consistent skill levels through training especially difficult, Calian helps you maintain skills at the required levels.

Increasingly, NATO HQs are more reliant on their own resources to plan and deliver more demanding and complex exercises with limited people and expertise. With the recent reductions in operational deployments, commanders are more reliant on training to build readiness.

Why use Battlestaff in a Box Training

Calian training meets the core needs of military training for HQ staff using the methods employed at NATO. Our modular approach is designed to your needs and requirements and will be discussed with you every step of the way to ensure your timelines are met.

  • Brings newcomers and augmentees up to speed early, reducing loss of operational capability during a standby period


  • Meets the specific requirements of your training audience
