I find the new IEDs quite interesting. My observations so far:
- very hard to detect - even by veteran engineers!
- take very long to clear if that's possible at all
- may even be triggered after being spotted DURING the clearing
process (!) - very realistic,
(I havent even managed to clear my IEDs yet BUT noticed after my engineer was sitting 4-5 turns facing one, not moving + hoping it would clear it, suddenly during AI turn: KABOOM! + I get the message: Engineer triggers IED! OUCH!!)
Best strategy seems to be buying a heavily-armored mine-clearing or dozer tank to move ahead of convoys...
