Yep - there are some OOBs that have trucks as an APC class as well, so any such will come in the APC count, not the soft vehicle count. The tallies are done on
unit class, not what something "looks like" - an APC U/Class based truck is thus an APC to the tally routine, and not a "softskin".
Personally - I never bother with the summary results. All I care about is the final credited score, and dont really care if it was from 24 tanks and 32 APC, or whatever. I already knew that from playing the game
