Pistol-grip launcher for flares. A tube launcher Flare Rocket version is Size 4, 1 kg, and Cr 100. Flares weigh 100 grams and cost Cr1 each. They have an adjustable burn rate, for up to 2 hours.
Flares are visual marker and counter-measure devices, either using intense light (e.g. potassium), smoke, or heat. Flares may be ground-based, dropped from an aircraft, fired from a flare gun, or fired from a rocket. If aerial, flares will have a simple parachute to provide maximum effect over a large area.
