As I understand, weapons can only be abandoned in the operations phase. On page 31 it is stated that "Any GO MMC, excluding WTs, or eligible SMCs can pick up an unpossessed SW present in the hex if the hex contains no enemy unit. Friendly GO units in the same hex can also swap SWs.".
I suppose an unit can't abandon a SW in the rally phase, since nothing is stated about it; or, if it can, we can't do it and pick it up by a GO unit in the same phase, what would render the GO units swapping rule futile. But, in the manual it is stated that a GO or Shaken unit abandons a SW if it leaves the hex. Isn't it allowed for a shaken unit to abandon it without moving, so that it is picked up by a GO in the operations phase using MPs or, at least, in the next rally phase? As it is, if the unit is shaken and we have no leader available, we'll have to move the shaken unit just to "unlock" the SW. Well, that is my understanding, at least, but I may be wrong.
