Currently, from my point of view, RTOs have only 3 jobs to do while groundside:
1. They can call drop pods containing tech-web stuff like plates, combat implants, stims, special ammo types etc. for marines to increase their combat effectiveness.
2. They can operate better with JTAC staff to call CAS, OB and Mortar (Squad Leaders can laze faster but they might be busy leading and coordinating marines).
3. They are the only way to communicate with Command when Telecommunications are not available (FOB squad forgot to take the Tcomms tower and crate or FOB is being breached and Tcomms is destroyed).
And they are in 2nd line of Squad's Lead which means they replace Squad Leader's role when he becomes KIA/MIA/AWOL. They are meant to be a support role and I think they have great responsibility for marines' combat effectiveness. But I think they can get another type of job to do as the ones I listed above happens rarely like you call droppods once new tech-web is bought which usually means every 5-10 minutes, CAS, OB and Mortar might not be available always and lastly, its really rare to see to having Tcomms not built unless engies were imcompetent and phones can be tricky to use when Command staff is understaffed. Here's my idea to make role better:
Combine squad's own launch tube located in Requisitions with the said squad's drop pod and make drop pod loadable with non-tech web stuff
I think RTO role might become an important role if their droppods can be loaded with non-tech web supplies by Cargo Techs. I mean maybe it can be good to combine their droppods with squad's supply drops? Here's my idea, so it goes like this:
1. RTO asks his Squad Leader about what marines need and Squad Leader tells him they need certain type of supplies or RTO himself observes the situation himself to find what marines need.
2. RTO informs the Cargo Techs they need certain type of supplies delivered to groundside.
2. Cargo Techs loads the drop pod with the said supllies when the drop pod is not in use.
3. When the said squad's drop pod is ready, Cargo Techs informs RTO about it.
4. RTO uses its ability to call drop pod and marines get the supplies along with the tech-web stuff.
This can make RTOs calling supply drops for marines with ease without having to laze, get the coords and then send it to Requisitions or SOs which takes time. I think this can increase the current RTOs importance by making them an aux-role that constantly calls drop pods loaded with supplies to keep marines suplied. And if there're no RTOs for certain squad, you can still use the old way to send the supplies.
Hope you like my idea! Thanks for reading!
