Here's some answers possibly even to the Q's you posed working from BT's list.
First off take a look at the political map (but now assume Inchin is Out World/Trexalon
Green).
You seem to be in SuSAG's good books currently. It would be fiscally unsound to pay you 5MCr just to do you in.
Remember these people have previous for disposing of unwanted/surplus mercs in a much more direct fashion...
Who are we fighting? Avastan have a TL 10 light infantry battalion as a "garrison"at the down port.
Where are we fighting? Avastan one parsec "north"
What are the Military Objectives? see the line I missed out

now added IC: a raid within one month to entirely destroy or put beyond use the pirate ground facilities on Avastan.
What are the Political Objectives? Well, who knows?
Why, if this is affecting hundreds of million of credits of shipping is only 5m being offered? Because
the shipping (if you can get possession of it intact) is the real prize (in every sense) here.
Does the 5m cover the cost of transport or is it separate to that cost? You are "all found" courtesy of a corporation (McClellan) for transport
and strategic comms.
Do we have any threat estimate for the opposition's forces? one static TL 10 Light Infantry Battalion
What is the Avastan Government's involvement? Unknown but their "odd" government might not run the star port
McLellan benefits. How? They are either merchants or part of the Trexalon alliance or both.
4DC and "The Shore" benefit how by being involved? See "the real prize" above and note Duran's comments IC and perhaps pro bono they are eliminating
other pirates
Who commands the 4DC, The Shore and the Aslan troops? Someone should ask that!
How do we get out of the contract? It's "Success Only" so once you are in - your're in!
What is a successful completion? Someone's definition of "entirely destroy or put beyond use the pirate ground facilities on Avastan".
What break clauses are there? There's a force majeure clause but that's it.
Under whose Jurisdiction is the contract being negotiated? Standard Imperial Contract Law (used as a baseline in 268).
The terms are open ended. Now clarified "within a month".
We could find ourselves unable to get out of this with no legal recourse. Likely if you sign then bail on the mission. This being the purpose of the contract.
Given the Merchant interest there will be considerable pressure to skimp recon, attack the front door and take casualties in exchange for time. The ball is in your court here.
The Imperium's definition of Piracy... One man's pirate is another's privateer - or pirate hunter.
Government 2 is a democracy. Law 0 is, by implication, a heavily armed one. Avastan is populated by "functionally democratic anarchists" and surprisingly stable outside the star port (which has its garrison).
API is a Collace corporation with heavy local influence on Collace. Historically Collace cut API off ... but may have reinstated their deal - but not officially.
