I doubt 100 APCs have been destroyed in any of the conflict areas.
Armored Personnel Carrier (APC) is historically not even an uparmored truck or troop carrier but a vehicle like the US Bradley specific in mission to carrying infantry into battle.
Light vehicles absolutely could be in that number easily. But not APCs.
APCs are typically used with heavier armor formations such as along Main Battle Tanks, AA, and artillery.
Classic strategy sees artillery moving forward into firing positions after MBTs have opened up a line of attack.
Light vehicles would be used as either recon or support, the APCs would be serving alongside traditional armor under cover of artillery, AA, and used in tactical situations such as capturing urban terrain for cover and moving to provide fire support to engaged recon elements.
I swear you idiots get all your info from CNN or Call of Duty. I hope if WW3 comes and Im drafted never to serve beside any of you dumb fucks.
