Marauder is a tier 4 patrol ship used by the Fringe Systems Resistance.
A somewhat dangerous opponent, Marauder's cannons and disruptors can pack quite the punch, so it's best to kill it quickly. A disruptor of your own will be practically necessary as Marauder relies solely on its shield and the innate durability of its cannons for defense. Point defense will be very helpful for helping to reduce Marauder's damage output, though it is unlikely that your point defense could shoot down all of Marauder's cannon shots. Don't bother targeting Marauder's disruptors - they're too difficult to hit, and the time spent destroying them could also be spent destroying its front. Target Marauder's ammo storage instead, as the small cannon in front of them is less durable than the large cannons. The resulting explosion will also damage Marauder's cannons, armor, and shield. From there, it will be easier to go for Marauder's reactor, but if you're feeling confident, targeting its cockpit instead will be a little tougher but also preserves more of Marauder's parts to salvage.
