@ alhoon: its very easy to change the space between the soldiers! its in the units_stats_land table in DBEditor
@T.C.: its also possible to mod flaming arrows: the only thing youve to do is to change the trail in the projectiles_tables to the rockets trail or the carcass trail(best is the rockets trail!) its in the last 2 or 3 columns. but theres only one problem: the trail is way to big for an arrow!!!

is there any way to shrink the trail! you are a well skilled modder, so who could give me advice if you do not???
im dealing with this problem also in this thread:
