When it comes to policy and politics eg. should we go to war?continue the war?,pull out of the war?and so on service people should NOT have the right to dictate or even amend policy even at General rank and above.
By all means specialist information (logistical,force levels etc.)should be unequivocally given to the government to assist them in their decisions ,but the decision is down to politicians alone.
Once military leaders are involved in the game then you’re on the slippery slope to military coups ,non compliance unless thesenior officers personal whims are indulged and much ,much more.
Further down the scale if the ordinary “grunt” starts to think he has some sort of say so in whether the war(any war)that he is fighting in, is justified or not then worst possible case you get mutiny and a refusal to fight at all ,or low morale troops (especially conscripts)deliberatly performing to the minimum standard allowable on the job.
Allow that situation to arise and then you start getting troops arguing that they should only fight in wars that they believe in and should be exempt from those that they dont .
Human nature being what it is many people would have "crisis 's of conscience about the conflict either genuinlly or cynically when they start becoming cold/hot ,wet, tired ,bored or missing their families.
Though my experience of the British army is that elite troops (Paras,marines,Spec. forces and the like) want to get into a war (any war without any interest in the political strategy behind their mobilisation ) and are bitterly disappointed if they are left out as you can ask ,I believe ,2Para their feelings at the start of Gulf 2.
But the poor sods from the logistical units who had to serve as infantry (to make the share of risk fair across the army)peace keepers to try and keep the two communities in Ulster from bombing and shooting the hell out of each other plodded on professionaly though they couldn’t care less about either of them.
Sorry to have waffled on so long, but finally even though a lot of politicians of whichever persuasion are usually dickheads, they’re the people we elected(including service personell)and they’re the people who tell us what we’re going to do and they speak for the civvy electorate but not the squaddies.(Mostly as they usually never bother asking us our opinions unless its a photo call ,but then again like we give a f~~~~)
