There is still no firing animation for the Mk6 mortar.
A mortar firing animation has been missing throughout the entire Arma series.
Firing the mortar in third person, or seeing it fired by others, looks terrible and is immersion breaking.
This really doesn't do the game justice because:
1 - The model/texture for the mortar is great and this missing animation makes it feel unfinished.
2 - Mortars are used regularly, given that artillery options in the game are currently limited.
3 - There is a huge number of different animations for Arma 3, many very similar - not a single one for firing the mortar.
4 - There has never been a mortar firing animation throughout the entire Arma series.
