I thought cirit would be interesting due to it’s smaller diameter and weight. Having multiple launcher tubes with similar or slightly shorter range would enable the crew to man and use them quickly.Why especially shoulder launcher of CIRIT? Shoulder launched Karaok and OMTAS aren't enough?
AFAIK first ignition of MANPADS / shoulder launched ATGMis reduced in order not to burn the operator ( also it would cause a fire in the warship)from backfire
And I believe they are cheaper in production.
