Hmm . . arrow marks ey ki bollen bujlam na . . but if u are talking about the STARS , that shows the level the units are in . . then u wud notice that some units have no stars .. or Arrows . . some have 1,2 or 3 .. ..

no cheat
ok . .
shiny .. havent u ever heard of the infantry rush my freind : ). . .
Method : Infantry Rush
Money : 10,000 - 50,000 . . doesnt matter .. depends on ur speed
1. Order another dozer.
2. The dozer you have, send it to the opposition's base
3. With the new dozer, get power and then supply centre.
4. The dozer u sent, let him built a gattling cannon in front of their barrack, or any other suitable place, inside their base, away from the base defence
5. After the cannon is built, go for a barrack and make RPGs

... 9 is enough
6. Use the RPGs to destroy things as follows :
a. the barracks
b. dozers
c. command centre.
If you are playing against GLA , they will have built a Arms Dealer already and have QUAD CANNONS waiting for you.. But nothing to worry about, just get another 9 RPG Troopers and attack the Arms Dealer with them.
Once you are done destroying all their unit production building and command centre, go get their supply centre .. u dont have to destroy base defence

.. . .
Am making a video of this . . soon :P . .
