Ablative armor and a grenade. Has a lot of HP for her rarity with a not so terrible evade, though YMMV between her and M38. Her main virtue is that she's the first 3 star you get from the story and they give you a pile of her so it's easy to stock up bodies. Only useful for logistics and cores once you have real tanks. If you happen across free PPS-43s, they're somewhat better.
