I see, might want to specify next time since I took it as a general tier list.
I got done watching a VC3 Let's Play and have made some interesting observations:
In VC3's account of the Battle of Naggiar Selvaria wipes out a Gallian Vehicle Squadron in 3 minutes (
https://youtu.be/yXj9UjIU5Is?t=1206, 20:05 to 20:25). Unfortunately the number of vehicles in a Squadron is a bit hard to pin down, but if you use the current US military as a yard stick you would get 42 or so tanks (counter opinions welcome). She would destroy a tank every 4 and a quarter seconds this way, or if she busts them 3 at a time like she did in VC1 she would be firing off a blast nearly once every 13 seconds. This only really helps pin down her rate of fire rather than improve her AP.
We also have Riela blowing a Ballistic Missile (the engine part at least) out of the air immediately after it launches (heading straight up), but this doesn't seem to be anything particularly out of the ordinary for her.
There is also that DLC episode (
https://valkyria.wikia.com/wiki/A_Secret_Power) where Riela was able to hold out against an Imperial force while she had to wait for the rest of the squad to arrive, and she does this with a Valkyrian knife. The only problem here is that this DLC remains untranslated, so we can't tell if she was able to tank small arms fire with the knife or just dodged it, or if the knife was just as taxing (causing her to overheat) for her as the standard Valkyrian arms or not.
In the VC3 OVA (based on the Isara DLC for VC3) Riela rapidly switches targets from a pair of artillery guns to the shells that they have fired (by raising the lance), and she does this mid-beam charge (
https://youtu.be/JZv75sBzuNk?t=65. Starts pulling out the lance at 1:05, starts charging it at 1:48, and redirects it at 1:58.). This is a great showing of both reactions, accuracy, and eyesight, and would further aid assorted Valkyria in intercepting projectiles and enemies (to a lesser extent) of similar speeds, and hilariously enough make aircraft in the VC world even more vulnerable than they already were. Attacking a Valkyria in a Dive Bomber or by strafing with a Fighter would be suicide.
Well I guess that is it until VC4 releases in the west. Have fun.
