@AWACSSince you know English ill just reply so, using Google translator to translate really kills me......

A reply this long would take me an hour to manually translate
1.No tank should ever equip spall liner, it is utterly useless since it only reduces HE damage by a static amount, not by %.
2.
If all of your team mates rush to one side, FOLLOW THEM, make a quick
break through then immediately go back to base, it is hopeless to defend
an entire flank by yourself.
3. The general rule is to not give your
opponent any opportunity to set up a static defense, once they do,
there is really nothing you can do.
4. First line to artillery should
be french, they are fast and mobile, which enables you to explore the
map for better shot angles, plus their fast reload make them extremely
forgiving.
5. Survive, survive for as long as you can all while doing
as much damage early on, 2000 damage dealt at the 3 minute mark is much
better than 5000 damage dealt at 14 minute mark, never camp, always be
active in trying to exploit weaknesses in enemy lines. In short, do as
much damage as possible as early as possible, all while living until the
end.
6. Very helpful mod, although i haven't been using it lately because i've gottena better computer but i think the game itself give a very nice silhouette with clear red marker so for me at least, it is fine.
