The projectile may be sabot launched. Constructions are described for igniting the tracer material directly or indirectly from the gases produced by burning of the main propellant charge when the projectile is fired from a gun, e.g. the RARDEN Gun of the Applicants. Example of suitable tracter materials and techniques for filling the said recess with them are also described.
