Monkeying around tonight and came up with this, opinions welcomed
MORTARS
Due to the nature of ground force operations they can rarely count on Starship based phasers to do much work for them. Be it because the ships must patrol away from the world or they may have even have left the system the ground force need a weapon to give constant indirect support. While artillery would be the best choice, ground force artillery units are few and far between and many companies end up relying on traditional mortars either using ultritium or photon grenade rounds.
Currently 2371, the ground forces use a ultritium mortar at the platoon and company level and a photon mortar at the battalion level. A typical mortar squad consist of 5 men, a squad leader (a sergeant) a Gunner (a corporal) assistant gunner (a lance corporal) and two loaders (both privates) with one mortar. Each member of the squad carries four rounds with them when entering combat
A mortar section consist of two mortar squads the 1st squad commanded by a Sergeant and the 2nd squad by a lance sergeant acting as squad leader. The Mortar platoon consists of 3 mortar sections commanded by a platoon sergeant who also commands the 1st mortar squad instead of the normal sergeant ( a full sergeant commands the 2nd squad in this section).
Typically a mortar section is found in a line platoon or a full squad at the company level; a mortar platoon is assigned at the Battalion level either independently or as part of the battalions heavy weapons company.
Starfleet Security procedures
Normally Starfleet security does not have mortars aboard ships or stations however their component parts are entered in the ships ordnance replicator and are able to be produced when needed. The parts are then assembled into a functioning mortar which can use either photon or ultritium grenades which are kept in the starships arsenal.
A typical medium sized ships security detail of up to forty personnel will have the needed personnel to form one well trained mortar section(Mortar detail). They well train using various methods including holo-deck training programs to keep their skills sharpened. Many such mortar details will fine themselves beamed down to militarily threaten colony’s in need of their services to strengthen local militia and security forces.
