Don't worry about Tim Collins Chappie, he blew his credibility with the military community a while ago.
To counter his argument I would take him on over the subject of money.
Most widows are living on a 1/3rd of the family income before they lost their loved one. Talk to Graham Knight he will give you a flavour of the degrading and humiliating questions the widows of the Kinloss tragedy have had to answer to qualify for supposed automatic compensation from the Government. Take Collins on and rub his nose in the mess he is trying to make from other people's grief.
I hope you take the MoD to the cleaners anyway. Most people understand that the MoD act like an actuary, the more expensive you make it for unnecessary loss of life the more chance they are likely to be proactive.
See if you can't get brave Mr Collins on a head to head, we'll see how brave he is then.
