Observations:
As far as "manoeuver elements" go you have 1st Squad [IFV] (Kit), Gaughan's Rangers [APC], Cavalry Troop [IFV-PD] (Jess). Of these Jess' squad (but not bus) is "short" being only one four man fire team (Kit has two and Gaughan three). Less the caveat as per my last all three elements are "mission capable" of military taskings in the field.
Support elements are Prerna's Recon/Sniper (short squad - one fire team in an APC) [also "mission capable"], Caxton's (HMG) squad, a redundant/fire support IFV (very flexible) with limited artillery (one medium mortar), gunship and ortillery support via HQ plus the HQ itself which has limited (infantry) combat power/security as is. NB This last is
not a weakness if operating out of starships but you now have Techs and a logistic tail to secure in the field.
The drone unit stretches its recon capacity from forward tactical recon to also cover HQ security. One option to ameliorate this situation would be a drone upgrade in quantity and quality (all now "second string" field gear (rotor drones) plows back into Bartizan security). Gun drones might also give the unit more flexibility and the option of another combat manoeuver unit (which is also expendable). Drones need Techs but don't draw any extra pay and are cheaper than robots. NB warbots per se are illegal in the Imperium and breach the (applied template in 268) "Imperial Rules of War".
Al the above puts your "boots on the ground" strength as a reinforced Company of TL 13 (averaged) Grav Infantry which is not too shabby at all. As far as District 268 goes SEMC is
a top shelf/high tech merc unit. The unit size means you likely want avoid attritional actions such as holding ground but then you are the guys hired to take ground and
not to hold it.
Things I think you found you wanted to consider (but by no means have to do):
For what you wanted it to do the mortar unit was always a calibre too small and a number of barrels (tubes) short of a "battery".
NB Whilst good in defence the mortars would need (armoured?) grav capability (per mortar) to keep up with the mobility of your unit - you may have evolved beyond them.
Direct fire support sleds/ indirect grav MLRS might do their job for you
or an atmospheric flight capable 400t warship / fighters.
Whilst the Blitzspear is your Dragonfly fighters (armed with ship to ship missiles) aren't optimal in this role. Also using multi MCr missiles to bust trenches upsets your accountant.
NB#1 If you added
just the one tiny tank platoon (3 tanks/SPGs) you could call yourselves
an Armoured unit!
NB#2 Tanks are expensive and break...

) thoughts above.
Troop tansport/Logistics vehicles (aka enhanced looting options) - you don't have any.
Understrength infantry elements as above.
Caxton seems something of a loose end. Maybe re-task him or give him another HMG as dedicated direct fire support and/or some AT/AA capacity???
HQ/Tech security maybe not an issue and ties into how far away you plan on operating from your ships.
Bartizan military upgrades: security troops/bots, AA/point defence, surface/local defence batteries, anti-starship batteries...
Bartizan civil upgrades: port facility upgrades. You'd rate as D at the moment - a fuel refinery and storage plus heavy workshops would upgrade you (and likely soon pay for itself).
Of course just spending your loot on drink/putting it in pile and burning it is easier!
The above is served up in the form of a "ready recap" rather than any kind of "direction"!
