Setting waypoints for an AI team to enter a helicopter/boat/vehicle of any kind will result in the lead unit walking slowly towards the vehicle, eventually boarding it. Other units will follow, with some of the rear men taking a long time to even start moving. If set to combat alert, it will simply result in them walking forwards at a tactical pace, just as slowly and with some units not moving. This needs to be updated to show a sense of urgency that you would expect entering a military vehicle. The solution could be as simple as changing the pace to a tactical jog when told to enter a vehicle.
