What do these mean here?
1. Does 'ranged against' here mean 'working against' ?

Shore-based anti-ship missiles, fast missile boats, midget subs and conventionally-armed ballistic missiles that threaten its enemies’ air bases, refineries and oil terminals are intended to be a deterrent against the more powerful forces Iran sees ranged against it.

2. Does 'make a great deal of trouble' mean 'to get maximum gain' or something ?

Iran will take decades not years to rebuild its atrophied conventional military capabilities.It knows how to make a great deal of trouble when it wants to, but a potentially dominant military power it is not.

Thanks
