@Jdublu69 If there is some kind of proximity equipment to put on the tank, I'd do that. In Planetside 2, Vanguard tank drivers all equipped proximity radar as standard due to rampant abuse of C4. You engage vehicles, then all the sudden are one shot because some assault class jetpacked over you with C4.
Its high time someone in gaming came up with a legit reason for C4 other than cheap vehicle kills. Create some on ground objectives that require C4 to blow up. Battlefield used to understand this back in Battlefield 2, and I think Battlefield 2142.
