I made a new tank shell (spectre shell) and gave it a contrail (ArtilleryBarrageTrail or something like it) and when the tank fires at a building or at a higher plain, it shows the shell climb up then accelerates to the target.

To put it simply, when it fires, the shell arcs high then levels and accelerates to the target. I used the spectre howitzer shell code.
