I normally deny explosives unless we do not have the man power to deal with a threat (4 or less on sim) Or they use cover as a way to lob grenades over the hills or use weapons that are not allowed etc. But the only explosives I allow are C4 or grenades. Maybe one Adjudicator at most. Also mortars are OIC discretion along with most ordo gear of that nature As for the jetpack im guilty of this too most of us are witch is why im no longer using it. gets me used to fighting in conventional means, removes temptation
