Force Field

Force Field is an enhancement for Damage Resistance found in the basic set.
==discreteness and order==
P108 notes under Affects Others how this can be a 1-time cost (instead of purchased in levels for allies affected for movement/transformation advantages) for a defense which has force field
P108 notes under Force Field's expanded description
:If you have multiple traits with Force Field, note whether you have one force field or several (and their order).
Extending Defenses (P173) notes other benefits.
==Switchability==
Some questions have been raised as to whether or not this enhancement makes DR switchable, since it can create some problems for people like making it impossible to eat food or don/remove clothing without lowering the field. Examples of protests to this include:
*2009
*2012
==Powers==
April 2006 GURPS Powers pg 108 gave some considerations if it was taken for Damage Resistance with both Area Effect and Affects Others:
:the force field impedes movement, too. Foes who wish to cross it must force their way in.
:Those who try this as a free action (allowed once per turn) roll thrust damage.
:Those who use Attack, Move and Attack, or All-Out Attack to blast their way in roll their attack’s usual damage.
Even though this is intended for AE and not the baseline version, these rules might explain how someone with a non-switchable force field might have rules for doing things like eating or changing clothing without lowering the field, by using the free thrust to get through it.
===Extrapolation===
This idea of movement giving a free attack could be expanded upon. For example, someone taking a Move maneuver (Full Move) should probably be more inherently "damaging" with their free thrust than someone moving 1/2 move (AOD:DD or AOA) or a step.
Furthermore the idea of movement giving free "damage" could be extrapolated into other ideas than pressing through force fields, such as pressing through grapples.
By the mere act of galloping at full Move, a horse should for example, cause difficulty for people keeping ahold of it, evne if they are not actively using Bucking Bronco or Break Free.
This would also realistically apply for example, if you are grappling an enemy and they are moved by other other enemy, such as if they suffer knockback. Knockback should not be a guarantee you lose your grappled oponent, but grappling opponent should not give them immunity to knockback either, or guarantee that you must be knocked back with them.
Unless someone lets go as a free action (and doing that in time should probably require a reaction roll) their grapple should be upset (lose CP) by their target getting knocked about by a 3rd party. In the process, having CP applied to you by a grappler should allow you to resist knockback better, already represented somewhat in the Brace option of Teamwork.
==Sorcery==
This appears to clarify that in combination with Reflection it is able to bounce back an Affliction (advantage) or Binding without it actually affecting the target.

unless you also take the Sealed advantage, any area effect that bypasses DR by dint of the Contact Agent enhancement or similar still affects you
