Ora boa noite,
Está na reta final a compra de 1 dos 2 candidatos:

M-2 Bradley
ou
Marder.
Cps,


Ó SS7;

Aínda não há noticias nenhumas sobre CAESARs e 777s que "referiste" há 15 dias (sem nenhuma notícia de concurso) e já estás a "referir" a "compra" de mais equipamento sem nehuma notícia de concurso?

É como os F-35?
É só escolher?

Não podes dizer mais nada sobre estes processos de compra marados do EP?

Se é assim, os Helis de Evacuação já deviam estar cá.

Bradley tem de ser a escolha óbvia...........

Bradley mais AMPV seria bem interessante
ou
Bradley mais ACSV G5


Marder penso que seria um erro para ser franco


CV90 seria a escolha óbvia -  e eu nem fui á página anterior para ver de que estão a falar.

Pois,
Alguns bonecos, andaram a brincar e as M holandesas já terão destino.
Agora é aguentar com os chassos até, pelo menos ... 2035 !
 ::) ::) ::) ::) ::) ::) ::) :bang:
Deixaram escapar "a compra"'? Para onde vão as M?


Eu imagino que isto se vai transformar numa grande festa/orgia   Marinha/DAMEN.

- Bimby
- Outra Bimby
- Modernizar VdG com equipamentos parecidos com os da MLU das BD.
- Equipar 6 NPO

**** Concessionar o Arsenal do Alfeite á DAMEN por 25 anos - penso que a Europa vai precisar de mais capacidade de estaleiros nos próximos anos ****   :mrgreen:

Já dá bastante dinheiro e abre portas para outros negócios.
Quem sabe se não dá outra BD?

« Última mensagem por André_021 em Hoje às 10:45:57 pm »
Esse numeros equivalem aos anos? Conforme os anos vão passando o salário aumenta e quando chego ao máximo subo de cargo?? Claro, depois dos respectivos testes. Algo que me preocupa também é o salário enquanto estudo, porque no fim do curso irei ter de me sustentar sozinho e vou ter de juntar bastante dinheiro visto que as rendas são bem altas... Os 5 anos de curso também contém o mestrado ou só depois dos 5 anos que posso tirar um?
