In the challenges and especially the one of the week, it is marked "destroy 15 enemy vehicles with anti-tank guns" in the challenge "Tank Hunter" no more no less, this suggests that we can do it in any game mode, both in solo modes and in multiplayer modes, and yet we can't, why? and why is it not possible to do all challenges in the mode we want. Each person does not necessarily play in all the modes available in the game and therefore cannot do the requested challenges, especially when they are not specified in which mode to do them.
