While a conga like TF2 would look absolutely silly, the coding behind it could probably be used to make a really sharp-looking /march. You could possibly even make it so that the person starting it can define the number of ranks with something like /march # (ie /march 3 for 3 ranks, /march 4 for 4 ranks), then whoever joins in will fall in as appropriate. Though I guess Orks probably can't march, and Eldar would find such a crude show of force beneath them, so it'd just be the IoM, Tau, and Necrons that march. Krieg could even goosestep when they do theirs. Though one possible hazard is that for weeks after its introduction the IoM will lose territory because they're too busy putting on parades to fight.
Not entirely true, we Commissars will be using it to create firing lines of cowards and dissidents so it would be because of us executing all the heretics and traitors in addition to dissidents...in fact you might be there too! See you at the tribunal.
