Infantry 20cm
Cavalry 30cm
Flyers 100cm
No matter if they are in regular o irregular formation.
But it is needed Line of Sight (LOS) to the target before starting the charge. You cannot charge nothing you are no seeing when the order is given.
We are getting more consensus on restricting Flyers to charge at over 60 cm.
Remember that ALL of (the points on) your stands ARE restricted to that maximum move into contact, and that ANY change in orientation of a stand IS actually movement and should be taken into consideration when making that move!
NOTE! and this is important! VERY important. There is no CHARGE order in Warmaster. The restriction on being able to charge is NOT on the moment of making that charge, but on the actual "start of moving into contact with enemy". LOS to the enemy is a consideration AT THAT POINT IN TIME, not at the moment of rolling the dice for the order!!
EG. I have a unit of archers in line in front of three units of knights in column behind them, the distance between the archers and the enemy is 21 cm. I indicate I am making a order on that brigade, roll my dice for a successful cast.
1) I move my archers of to the side (probably trying to get them to line up to shoot a supporting line of infantry if that would be my target for the knights charging in.
2) the frontal unit of each of my stands of knight now has LOS on the enemy (with 23cm! between the opposing units)
3) as the order to the brigaded unit was successful, and my unit(s) have LOS on the enemy I now fulfill the conditions to "move into contact" aka Charge!!
4) I opt to start with my middle unit, so I determine the closest enemy stand and move into center-2-center contact
((a) this is probably a direct move forward, so I move 23 cm)
((b) remember not to forget S&S should the charged unit have missile weapons
5) I pick the second stand of my charging unit. this one moves
- up 8cm (it needs to clear the adjoining units!!)
- slightly over 19 cm into corner to corner contact with the first stand placed (measure this or use Pythagoras!)
- directly forward 4 cm, into contact with the enemy
OH WAIT.......
