Perhaps it's time to lose this part of the event? It has been in the Olympics since 1912 and the world championships have been held annually since 1949. I don't think the word Modern can be applied anymore. Modern horse training considers the welfare of the horse, something that has changed since 1949. To take an animal and give it a rider that it doesn't know or trust, that is has no training experience with and ask it to perform on the world stage where team pressure is huge for the rider, is not kind. It is also dangerous for the rider. There is no partnership or care for the animal, it isn't owned or cared for by the team. There is no relationship just the need to use it like a bike or a gun to win a medal. It is time to move on remove this outdated sport. If it is based on a military need to grab a random horse and ride to safety then that rider will have had no consideration for the horse and ridden the life out of it to save his own, quite understandably. Time to make a change, perhaps this might help to bring it about.
I think it's the entire point of the event - and that's what has been lost from it.
Having the horsemanship at the beginning means that everybody will have to be a better rider because if you can run, shoot at targets, go for a swim, wave an épée around, good for you, you're fit and able to learn to chuck your body round in different ways. But to be a rider, you also need the ability to stay calm and project that composure and confidence in a way that a horse, any horse, can understand.
Which was exactly why it was developed - no point in being able to defeat an enemy in single combat if you're going to be sat ten foot from the enemy encampment when the next watch realise the guards have been killed, wailing and crying because the mean old pony has thought 'who is this dickhead and what the hell do they want me to do?'
Most of the events are a plain and simple strong, fast, balance, moving oneself and one's allocated pointy or heavy things competition. This is doing things for a purpose and still being the best at it.
