Movement - Boot Camp

In the movement phase of a turn the model vehicles are moved.  Depending on the orders given at the beginning of the turn players move their tanks in a specific order.  Tank platoons (and companies) that were given Charge, Rush or Bound orders go first.  Tanks moving full must be moved over half their listed movement speed.
Players on both sides that have any tanks moving at full move speed must move in this segment. Next all tanks having orders where they must move half speed go.   These must move more than 25mm.  None are allowed to move more than half their allowed movement.  Lastly tanks that have orders where they move no more than 25mm.

If a group of tanks start more than 500 away neither side goes first, they move at the same time.  If the tanks are 500 or under from each other one player on each side rolls a D10 for 'Initiative'.  The Initiative table gives some nationalities and troop types a initiative bonus.  Add to the die roll the bonus number and the total that is the highest gets to go second.   The platoon can react slightly to what their opponent is doing.   They still have to follow their movement orders but they can at least steer their tanks to take advantage to this initiative.

Obstacles like small walls or streams cost movement speed factors.  This is reduced from the total straight line distance a tank moves but counts as speed.  Also, some terrain, like woods and climbing up hills reduces the distance moved by costing twice as much to move.  The total speed factors used is what is important, not the total straight line distance.  If the M4A3E8 Sherman tank example were to move 85mm in a woods it would be moving at full speed even though the straight line distance is only equal to 1/2 the speed.

The speed is listed as two numbers here.  The first number is the cross county speed and the second is the road speed.

Sighting - Boot Camp

After moving all of both sides tanks and other troops it comes time to determine if they can sight the enemy.  Usually if something was sighted in the previous turn it will be automatically sighted or kept in sight if it didn't move away.  There are exception an we will see one in the following example.
1.  Tanks and other armored vehicles are organized in platoons.  If the platoon is doing the same thing and looking in the same direction they can all try to spot together as a group.  The three Sherman tanks and a Firefly tank are all stopped in the edge of a woods.  They all have their hatches open as their tanks are unbuttoned and the commanders are searching for the enemy.
3.  Let's say there are some enemy out there. Two enemy German Tigers tanks are moving hull down in a gully some 600mm away.  In addition three enemy Mark IV tanks have just moved out from a village and into some woods 850mm away.
4.  Using the Sighting calculator the starting row for the four stationary British tanks will be the dark blue line.  This states 'Stationary Unbuttoned' and equals 40 sighting factors.  Then add or subtract all the factors that apply for each group of possible targets. 

Far left- British tanks sight.
Left - Tigers move hull down behind trees.
Right - Mark IV tanks move in open from town.
Far right - Mark IVs end move in small woods.

5.  For the two moving Tigers: There is a narrow line of trees (10-15mm) between them and the British.  For moving more than a shift move (+15)   For hull down (-8).  For seeing into or through foliage (-5). Size of target tank (+1 for size 1).  Give a grand total of 43 factors.  This equates to a visibility distance of 1025mm.
6.  Next figure out the Mark IVs tanks moving in the open or into trees.  Figure out both the 'in the open' distance and 'in the woods' distance.  Starting again at 40 factors.  When the Mark IVs are moving in the open (+15). The size of the Mark IV is 0 so no additions.  This gives a total of 55 or 2200mm.  But what happens to the Mark IVs when they go into the woods.  The +15 for moving still applies but now there is a -5 for seeing into foliage and -10 for the tanks actually being in woods.. Totaling 40 factors or 800mm.

This section of the Sighting Calculator show the four starting rows.  The dark blue row is for an observer that is stationary and unbuttoned.

7.  The spotting tanks must make a variable sighting roll on a D10.  There is only one roll made per spotting group no matter how many targets or groups of targets there are.  To this die roll number the sighting group gets to add +1 for each friend (up to 4) helping sight.  The roll is a '1'.   But with +3 this goes to 4.  On the variable sighting table this is one half normal visibility distance.  The sighting distance for each situation is halved.  Which means for the hull down Tiger group at 600mm away half of 1025mm (513mm) visibility distance and is not enough see them.  But for the Mark IVs moving in the open at 850mm range half of 2200mm (1100mm) visibility distance is enough to see them.  But what about when they get into the woods?  Ordinarily they would not be seen moving into the woods if they hadn't first been seen moving there because one half of 800mm is only 400 and is not enough to see the 850mm to the woods.   
But since the Mark IVs had been spotted previously they would have to disappear not to be seen.   The only way to disappear is to be impossible to see by either blocking the line of sight or being over two times the normal sighting distance.  If there's still a little possibility of sighting (by rolling a '12' or more on the variable sighting table) then they have not disappeared.
The best variable sighting roll possible gives 2 times the normal visibility or 2 x 800 = 1600mm.  1600 visibility distance is greater than the 850mm range so the Mark IVs remain in sight as they move in the woods.

8.  What will happen the following turn if the Mark IVs remain stationary in the woods?  In this case the base sighting factor from stationary unbuttoned observers is still 40.  Tanks in woods (-10) and through foliage (-5) totals 25.   This is a range of 225.  But 2 x 225 is 450 maximum sighting distance.  This is less than the 850 distance to the Mark IVs.  They will in effect 'disappear' from sight.  And unless they move or fire from this woods they will not be seen.
9.  The British tanks will still know there's some enemy tanks in those woods, but not their exact locations.  Not enough to fire their guns at them.  But if they had some sort of link to artillery or air support a call could be made to fire indirectly on the area of the woods.
