Can you play Orders multiple times from 1 unit?

Example: if you build Sunspear Royal Guards + Obara Sand - you'll have 3 orders. So, can you use reckless charge of Obara, then use shield wall when she gets hit and then use her last order Martial training, say, from using swords tactic zone - and all that in a span of 1 round?
Is that legal?
The rules doesnt say how many orders can you unleash exactly, per round.

There is no limit to orders, except that they can each only be used once per round.
