I have been reading several topics recently concerning ERA. It seems to me that the concept of explosive defensive munitions is dangerous to both the exposed vehicle crew and dismounted troops nearby.
For example, I was watching video of T-72s in action in an urban environment - the camera was fixed to the turret top behind the ERA boxes, and it occured to me that if the TC had his head out the cupola and the ERA detonated this would not have a happy outcome. It may not be shrapnel wounds, but close proximity detonations can cause burst ear-drums and detached retina for example.
Another example is the talk of fitting IFV/APCs with ERA. I see two problems here - one is ERA exploding in close proximity to friendly dismounted troops. The second problem is the relatively light construction of these vehicles and subsequent shock/personal damage.
I have three questions:
1. Is there a Master Arm switch to de-activate the ERA ?
2. Is it tactical practice to operate ERA equipped vehicles always buttoned-up i.e. all hatches closed ?
3. Are the ERA effects on personal modelled in Steel Beasts ?
Tactically, I see the side using ERA would be tactically disadvantaged from the start by being forced to operate with restricted awareness.
