At the least - a Leader should be able to opt in/out. A member should definitely be able to opt in/out - otherwise the leader may not know if they are available or not to opt in/out.
Questions would be - should a leader be able to opt a member in that opts out? In general I think not - but what if they had 20 ppl and 19 opted in? Maybe the leader could opt the 20th person in and tell them not to worry - no need ot attack, we just need you in the count.
Also - Should CO's be allowed to opt other members in/out? I lean yes but could go either way.
