In the following video you can see how the African Matabele ants (Megaponera analis) they take care of the wounds of their fellow soldiers injured in clashes with other termite species.
Help in combat
No other insects are known to cover the wounds of their comrades, but when an ant is injured in a fight, he calls his companions for help excreting a chemical that causes them to take their injured partner back to the nest.
In addition, ants treat the open wounds of their wounded companions by "licking" them intensely, often for several minutes.
Erik T. Frank, Marten Wehrhan and Karl Eduard Linsenmair, from 'Julius-Maximilians-Universität Würzburg' (JMU), in Bavaria, Germany, explain this discovery in the magazine Proceedings of the Royal Society B.
The most curious thing is that it is the wounded ants themselves that decide, motu proprio and for the good of the colony, not be rescued if your injuries are too serious: for example, those that lose five of their six legs.
