If there's one thing in LL that always struck me as particularly vague and ambiguous it's the section on combat movement. First they begin by stating that there's "two special forms of movement possible in combat", and then refer to the rules mentioned in the "Movement in Encounters" section (which I assume are normal movement and running). They then add that there's "additional movement types" and discuss the Fighting Retreat and the Full Retreat. Broadly speaking, those extra maneuvers are then explained as such;
A fighting retreat allows you to move backwards at 1/2 your encounter speed. A full retreat allows you to move backwards at greater than 1/2 your encounter speed, but you forfeit your attack this round, and your opponent attacks with a +2 to hit.
Reading and re-reading this section leaves me with a few questions, and I'm not entirely sure how this is meant to be played. Are we suddenly expected to keep track of who's moving forwards and backwards in combat? Couldn't you just turn around first, and then move? Also, the +2 attack that your opponent gets; does that happen immediately, or whenever it would normally occur in the round? Almost sounds like an "attack of opportunity" from 3.5. It's interesting to point out in the combat example from the Mutant Future rulebook, all combatants get a free attack (with +2 to hit) against the fleeing flies, but no such scenario is present in the LL combat example.
I should point out that I'm not too concerned with these questions, as I intend to use the RC rules for combat maneuvers (Fighting Withdrawal and Retreat). I'm simply making an observation here.
