Adjusting the charge rings on mortar shells to change detonation range requires holding the interact key (F) and scrolling the mouse wheel while holding the shell. However, there is no HUD hint or keybind prompt indicating this control scheme to the player.

Adding a clear keybind prompt on screen when holding a mortar shell (or streamlining the interaction) would greatly improve accessibility for indirect fire support players.

Rationale / Why it's needed:

• Improves Discoverability & UX: New or casual players frequently struggle with mortar mechanics because the required key combination is completely hidden.

• Reduces Friction: Prevents confusion during active combat when adjusting charge rings quickly is required.

Suggested Implementation:

• Add a visual HUD keybind prompt (e.g., [Hold F + Scroll] Adjust Charge) when holding a mortar shell in hand.

• Alternatively, evaluate simplifying the charge ring adjustment mechanism via an interactive radial menu or contextual action.
