*Observed*
When you approach a dead soldier you get, depending if he has compatible ammo to your weapon a "Rearm" default action or if you walk to his dropped weapon a "Take <weapon name>" default action.
Both share the same action icon, so you might get surprised by changing your weapon instead of rearming.
*Expected*
The action icon for "Rearm" and "Take <weapon>" should be different and recognizable for the one or the other action.
