How to transport mines in a truck or bmp

Hi everyone

SUMMARY

How exactly do I place mines in the back of a truck or bmp for transport?

DETAIL

I'm stuck on the OFP:Resistance mission Counterattack where the tanks rush
you and you have tanks of your own.

I can't place all the mines in time as I have to carry them by hand myself
to the chokepoint

Is there any way of transporting all the mines from the ammo crate in the
BMP. If so *how exactly do i place mines in the back of the truck/bmp* so i
can carry it to the front?

I have tried over and over to work out some way of picking up a mine and
putting it in a vehicle but I can't seem to work it out as it does not
appear in my list of actions. The only option I get is "drop mine".

Please reply to the group not to me personally.

Thanks,

Gray.
