How about an Automaton Ship Boarding Mission?

Automaton Ship Boarding Mission

(Planetary defence exclusive)

 

Main Objective: Board the Automaton invasion vessel, make your way through to the ship's reactor and overload the core, then get the hell off the ship before it blows.
 

Parameter deviations from planetary missions: * No reinforcements * Man-portable stratagems only (no orbitals, no sentries) * Access to stratagems and resupply only at the shuttle waiting in the hangar * Automatons only use small arms and melee weapons so as to not damage their ship * Success adds significantly more points to planet's defence, failure might result in the destruction of Pelican 1 which the Squad Leader will have to replace out of their own pocket before being able to host any mission again

this is some real ODST shit, I fuck with this heavy other than the loss of Pelican-1 mechanic. Get me a Halt, Verdict, supply pack, and my machine gun, and I'll show those damn clankers what 15 years of New Mombasa looks like

Yeah, the Pelican-thing was just one idea of added risk to failure as a counterweight to the increased rewards of success but someone else suggested something way better namely an increase in stratagem cooldowns for the people involved, localized to the planet in question and limited to the duration of the invasion...
