The HPS User's Manual states that when the <b>Manual Defensive Fire</b> option is used (that is, putting the game into phase-based mode), that "an infantry unit can only change to Line formation before it has moved although it may move after changing to Line formation." The opposite formation change, from Line into Column, is also regulated by this rule.
This rule is a throwback to the original TalonSoft Battleground games. If you have an original, printed Player's Guide to these games, you'll find the following pronouncement under the <b>Formations</b> entry of 2.0, the <b>Basics of Play</b>: "You can change a unit's Formation during its Movement Phase." The guide then says, "(<b>IMPORTANT</b>: <i>Infantry</i> and <i>dismounted cavalry</i> can change Formation only before it begins to move.)"
The exact reason(s) for this particular ruling are nowhere to be found. Neither John Tiller nor Jim Rose made specific comment in the Battleground guide as to why this rule was established. But because the game was structured on what is now referred to as a "phase-based" program, one may infer that unit formation changes were simply regarded as another "first-in element" of programming; in other words, it was structured as a prerequisite condition of the particular movement program code. There was certainly no historical reason to so structure it!
The new HPS engine, however, is much more elaborate and flexible in its program, and allows units to change formation at any point in its movement cycle. An infantry unit may move in Column formation and then deploy into Line formation provided it has enough movement points available. It may also move in Line formation first and then change into Column, again only subject to the movement point capability. As an <i>option</i>, players may elect to play their game under the old Battleground system (phase-based) if they prefer, but they will be stuck with the same, ahistorical restriction to formation change if they do.
I am a great fan of the phase-based system, but I have always chafed under the unrealistic formation change restrictions in both the original Battleground games and in the HPS optional version as well. The 20-minute game turn provides ample time in my mind for a unit to make a formation change at the beginning of the turn, in the middle of the turn, or at the end of a turn, provided that it has enough movement point capabilty to do so! At least that is what I think! Is there any real reason not to have it so, or to have it reserved exclusively for turn-based play?
I would like to hear some other opinions on this and whether a majority of players feels that the restrictions on formation change in the HPS <i>phase-based play</i> ought to be either completely dropped or made an option.
