If you want real 100% milsim, here's a perfect game:
Tan team is 50 dudes.
You're told to show up to a base where you'll immediately receive further orders.
Wait 4 hours.
Get orders there's a group of 4-6 rebels hold up in a shack 20 miles south of here.
Ride on deuce for 19 miles.
They have RPGs. Walk the last mile.
Show up and there's nobody there.
Go back to base.
wait for orders for 6 hours.
Have a single random mortar land in base, have everyone lose their shit trying to find a mortar team that's already fucked off.
Wait some more.
Get orders to go link up with a battalion that's going to siege a city.
Get to the city, all the work is already done.
