It's quite hard for me. I'll mention a few:
Diplex, as he lead the 77y arty back in MM which i was in and he did well to promote skilled and overall good players for arty, as well as the 79th->33rd etc, all of which where pretty fun to be in.
Aztir, as even to this day he continues to lead the 77y, he lead the line infantry well back in MM and i think he still continues to do well for the 77y overall. I remember when i first joined he was promoted to LCpl, now hes all grown up
.
As well as K.G, who was the leader of the cav detachment in Diplex's reg's. After they were all gone a small community that came out of it formed the 9te which he was one of the officers there. I'm still in contact with him today
although we don't talk that much.
And an honourable mention to Crumpet who keeps a good mix between discipline and enjoyment in linebattle's and a feeling of being welcome in the reg outside of them.
