Strategies:-
I put 3/5 because the Chimera has got very good HP & Armor but their damage just suck. It totally sucks. That's the price for being a versatile Mobile Unit. However, Chimera are fast and since they have good HP and Armor, why not put them to use and attempt to capture the poc? Well, thats what I am going to discuss.

Poccing:-
Fit in as much armor and engine as you can and take off the weapon. The weapon is just a waste of space and weight. You might as well spend it on phasic plating or something better. Chimeras laser isn't anywhere near a moths so you don't need it. What you need is HP and Armor. When you are poccing, Chimeras are better off as last tick poccers. That means that the PoC is about to be captured but there are a few poccers left. Use Chims. Chims are relatively fast and can get there on time while the moths are still stuck at the portal. Just make sure you get there on time.
