I know i haven't been active on the forums much, but i just wanted to first off say what an amazing community! Very cool to see so many mechwarrior's sharing ideas and thoughts

Anyways.. I have always been a huge fan of the Battletech CCG game, and recently got back into it with a couple of good friends. Everything rule wise seems to be remembered well, but i pose a couple of questions to the community in order to clarify my thoughts.
1. A mech can be sent to Guard only on his Mission Phase, when a mech is placed on guard for a certain target.. it is for all intensive purposes, permanently blocking.. unless pulled off of guard duty at a later mission phase.
-if this is the case, an opponent could not declare the stockpile a target unless the mech was defeated first? And if the mech guarding is challenged, does the defending player still TAP this mech in return? or is blocking always presumed because of the guarding nature?
2. If a Guarding mech has the Alpha Strike ability, if said mech uses this in a combat, the guarding mech would be depleted. If a guarding mech is depleted, is the site it is defending now open for an attack in the same mission phase?
That's all i really had to ponder about from our last game, i would love to hear your ideas and interpretation of how this would work

Cheers
