Hello!
Unit identification can be very difficult in this case. Soviet 14 VA (14th Air Army) supported 3rd Baltic Front in the Summer 1944 assault. The air army was mostly involved in Latvia but participated also in the battles over Southern Estonia (my focus of interest).
A Soviet-era Estonian book mentions that 14 VA had 12 Shturmovik regiments in Estonian battles. The same may hold true also during the battles around Ergli, Latvia. BTW Rudel was also shot down over Ergli!

14 VA organic attack division seems to have been 305 ShAD which consisted of 175, 237 and 955 ShAP

But the mixed aviation division 280 SAD also had two Il-2 regiments: 606 and 958 ShAP

Remainder of the Il-2 regiments were from 7 ShAK (Attack Aviation Corps) which had 2 or 3 divisions and numerous regiments. I have not been able to sort out exactly which regiments were fighting with 14 VA during the Summer 1944. I thought I had a list prepared by a colleague but did not find it.

PS There was lots of Zavod 18 Il-2s in the 7 VA units, not only from 30 Zavod.
