Editing Warhammer 40,000/Tactics(2E) (section)

===Movement===

The 2nd Edition Movement Phase has more in common with Warhammer Fantasy than later editions of 40k. The key things to note:

* You declare charges before anything else: A unit may charge one or more enemy units, and a charge move is a straight line equal to twice the model's move characteristic.

* All "compulsory moves" (fleeing troops, out of control vehicles, etc) are resolved next. Models resolve their charges afterwards, and then the remainder of units "move as normal."

* Models that did not Charge could Run (move double movement speed in a straight line), move as normal, or forfeit movement in order to enter Overwatch. 
**'''Hiding:''' If a unit was composed entirely of small enough models (Terminators and cavalry are too big!), did not Run, and ended its move in Cover, it could Hide. Hiding works similarly to Mordheim in that you cannot be targeted by shooting until the enemy gets close to you. You can spot a hidden model up to twice your Initiative in inches away, so a Space Marine can detect hidden models within 8". However, even after spotting a Hidden unit, it merely becomes Detected: although the spotting unit can see without issue, other friendlies can only attack with AOEs (flamers/blasts) and even those only hit on a 4+ on top of normal rolls. A unit exits its Hidden/Detected status the moment it Runs or Shoots (even via Overwatch).

====Overwatch====

A unit that forfeits its movement during the Movement Phase may enter Overwatch. (Note: Vehicles may still move and Overwatch). This section is complicated enough to have its own section, will fill out.
