How good is this formation?

ST-ST
AML-AMC-AMR
MC
DMC
DC-DC-DC
GK
And which orders should i give to use it?

very weak formation without any midfield.Opponents easily can beat you with two or three midfield and attacking from the flanks.Change the tactic.

does it get better if i change those AML-AMR for ML-MR? or change that DMC for another MC?

and if i wanted to keep this formation, which orders should i set??? please any help is much appreciated :)
