I knew it was high Joe but put 100+ because I didn't know what the final number was before he went down strafing.
And yes, Gabby was killing Rall types not Rall prey types. It was the 56th that put him out of the War.
Anothe point about Gabby - had the 4th converted to 51s his numbers surely would have been a lot higher as the Penetration/Withdrawal Support missions limited 56th to far fewer encounters April - July
