Read full description

The Review Toolkit is the first mobile application specifically designed by the United Nations to make knowledge sharing methodology accessible to all military and police personnel, training centres and academies. Users can capture, analyse, review the successes, innovations and challenges from their operational experiences, to improve and optimize training, preparation and support of their future deployments. All successes and failures offer vital opportunities to learn and improve. At all levels of any organization there is a responsibility to come together and share experiences and lessons learned. This is especially critical in complex and rapidly evolving operational environments, including United Nations peacekeeping operations. The good practices and lessons developed by those previously deployed are essential not only to training and preparation, but also to the development and implementation of tactics, techniques and procedures of future military contingent and formed police unit (FPU) personnel.. The Review Toolkit is an effective, secure and user-friendly way to optimize your knowledge sharing practices and can complement existing information-sharing systems; it will serve as a blueprint for systems that are yet to be developed. The Review Toolkit is produced by the United Nations Light Coordination Mechanism (LCM) of the United Nations Department of Peace Operations (DPO) with the support of the United Nations Department of Operational Support (DOS) and the Department of Global Communications (DGC).

Sololearn's advantage is update cadence (every 2 weeks vs every 3 months) and ratings volume (82K vs 3). On price, rating and device support there is nothing between them.
