We should be able to choose between land mines and grenades. I have done a couple posts on this and what i have said is that
1.you shouldn't be able to put land mines in a certain radius from the intel.
2.You should be able to shoot them to make them go off
3.Only a certain amount in a radius
4.TWO LAND MINES PER LIFE NO REFILLS
5.Teamates shouldnt set them off
6.Only your team can see your teams land mines
7.Same damage as a grenade

ADD SOME MORE

C4, Flak Jacket etc

More damage than the grenade?

Since you can't throw it
