### Variants

The 40x46mm SDC indeed offers a range of ammunition types beyond just high-explosive (HE) rounds. Its versatility allows for the deployment of various specialized rounds to meet different mission requirements. Some of the ammunition types that can be fired from the 40x46mm SDC include:

Its standard 10-meter safe arming distance for HE rounds ensures safe deployment in various scenarios.
* **Smoke Rounds**: Smoke rounds release a dense smoke cloud when deployed, providing visual cover and obscuring the battlefield. These are valuable for concealing troop movements or creating a diversion.
* **Illumination Rounds**: Illumination rounds are equipped with flares that illuminate the area, making them ideal for night operations or to light up areas for reconnaissance.
* **Incendiary Rounds**: Incendiary rounds contain flammable material that ignite upon impact, causing fires and inflicting thermal damage to equipment and personnel.
* **Training Rounds**: In training and practice scenarios, inert or training rounds are used to simulate the weight and trajectory of live rounds without the explosive effects.
* **Less-Lethal Rounds**: Some launchers are capable of firing less-lethal or non-lethal rounds, such as rubber ball rounds, bean bag rounds, or foam baton rounds, which are designed to incapacitate or deter without causing lethal harm.
* **Tear Gas Rounds**: Tear gas rounds release chemical agents that cause eye and respiratory irritation, making them effective for crowd control and dispersing unruly crowds.

The 40x46mm SDC's ability to accommodate this variety of rounds makes it a valuable tool for military and law enforcement personnel, as it can be adapted to suit different mission objectives, from crowd control and illumination to anti-armor and lethal engagement, all while maintaining a safe arming distance of 10 meters for HE rounds.
