The Israeli and Swiss militia based armies have good leaders at that level as everyone stays in and continues training and professional development. Its a lot different from the usual conscript based army. That isn't to say it can't be done, but you need a good sized cadre of Sr NCOs for best results.
That the Swiss have a good military is pure speculation as they haven't fought.
I think the Singapore army will disintegrate upon contact but that, is also pure speculation, because we haven't had to fight.
Just an observation.
